• Tens of thousands of passengers are reportedly canceling flights with Jeju Air, South Korean media said.
• That's after one of its jets crashed on Sunday.
• 179 people — almost everyone on board — died in the crash, officials said. The cause is being investigated.

Passengers with the South Korean airline Jeju Air are canceling tickets after one of its aircraft crashed, killing 179 people.

The airline said that 68,000 flight reservations had been canceled as of 1 p.m. on Monday, South Korea's Yonhap news agency reported.

Most of the cancellations happened after Flight 7C2216 crashed on Sunday.

Some 33,000 of the cancellations were for domestic flights, and 34,000 for international flights, the report said. Jeju is South Korea's biggest low-cost airline.

The Boeing 737-800 crashed while trying to land at South Korea's Muan International Airport at 9:03 a.m. 179 of the 181 people on board were killed, local authorities said.

Footage showed the plane slide on the runway before it came off, hit a barrier, and burst into flames.

The CEO of the airline, Kim E-bae, issued a public apology: "Above all, we express our deepest condolences and apologies to the families of the passengers who lost their lives in this accident.

"At present, the cause of the accident is difficult to determine, and we must await the official investigation results from the relevant government agencies. Regardless of the cause, as CEO, I feel profound responsibility for this incident," he said, according to The Guardian's translation.

On Monday, most of the homepage of the airline's website had been cleared. A black banner on its English-language version said: "We deeply apologize to all those affected by the incident. We will make every effort to resolve the situation. We sincerely regret the distress caused."

Mass cancelations have happened before after major accidents. This includes customers canceling bookings with Malaysia Airlines after two deadly incidents in 2014.

Investigations into the South Korean crash are underway and no cause has been concluded yet.

A bird strike is one possible factor, with an official in South Korea's transport ministry reportedly saying the airport's control tower issued a bird strike warning before the crash.

But experts are skeptical that it would likely be the only reason, as planes are designed with fail safes and with bird strikes in mind.

Video footage showed the plane landing without its landing gear deployed.

Why that was the case is not yet clear.

• The US military has warned that lifesaving "golden hour" care may not exist in future wars.
• The experiences of Ukrainian soldiers reflect those warnings.
• Getting treatment can take hours, if not days, leading to lasting injuries, amputations, and deaths.

American generals predicted years ago that the intensity of future wars could upend lifesaving evacuations and medical care for injured troops.

That prediction is now a reality in Ukraine, where soldiers often can't get proper medical care within the "golden hour" — the critical first 60 minutes after severe injuries when treatment can increase chances of survival.

"Until there's a real concrete answer for drones, it's going to continue to be pretty hectic when it comes to that type of care," a combat medic with a foreign volunteer unit in Ukraine told Business Insider.

The medic, who uses the call sign Tango, has front-line experience with Chosen Company, including an ill-fated fight in the village of Pervomaiske where his team was devastated by Russian indirect fire in July 2023. Despite his own injuries, he helped provide first aid to a handful of wounded men, but they had to wait hours for more extensive care. Two men didn't survive.

In Ukraine, swarms of drones and constant artillery strikes complicate timely evacuations, contributing to the war's soaring death toll and the severity of survivors' injuries.

Asked in 2019 by Congress whether the US military would be able to evacuate wounded troops during the golden hour in future conflicts, Gen. Mark Milley, then the Army's chief of staff and later the chairman of the Joint Chiefs of Staff, gave a grim response.

"Probably not," he said.

"We'll try," he added, "but I'm not guaranteeing."

Other military leaders have expressed similar concerns. "You may have previously heard a discussion of the 'golden hour,'" Maj. Gen. Anthony McQueen, now the Army's deputy surgeon general but formerly the head of its Medical Research and Development Command, said last year. "We're moving more to a 'golden window of opportunity.'"

On any given day in Ukraine, wounded soldiers may be stuck near the front lines for hours or days and can be evacuated only during a break in the fighting or in the dim light of dawn and dusk.

"Here in Ukraine," a US Army veteran fighting in Ukraine who goes by the call sign Jackie told BI, "we have a golden three days."

A struggle to evacuate

A Ukrainian combat medic who requested anonymity due to the sensitivity of the work she does told BI the struggle to quickly evacuate was "a big problem" that had only worsened with drones becoming more prolific. "Two years ago," she said, "it was a totally different war from what is going on now."

An estimated 1 million people have been killed or injured in the Ukraine war, with casualties stemming heavily from drones and artillery.

Cheap drones swarming the skies over Ukraine's battlefields can severely delay medical evacuations. The drones serve as aerial eyes for artillery, bombers that can drop grenades, and precision-strike munitions.

The Ukrainian medic said Russian troops target vehicles known to be carrying out evacuations, a war crime about which other Ukrainian troops have repeatedly raised concerns in this war. Russia did not immediately respond to BI's request for comment on the allegations.

They aim for the combat medics, she said, because "if you kill a medic, it means that you killed thousands of soldiers," or all the people they might have saved otherwise.

"If you look special or different, you are going to attract a drone," Tango said. "That goes especially for evac, and they specifically target medical vehicles or anybody with a backpack. You never wear a medic patch on the front line. That's a guaranteed drone strike."

Drones are only one of the war's many causes of bodily harm and death. A 2023 medical study found that 70% of Ukrainian war injuries were caused by shelling or rocket fire.

The Ukrainian medic said first responders sometimes reach injured soldiers quickly but can't evacuate if nearby roads are controlled by Russians or exposed to drones.

That can mean waiting hours or even days.

Extended delays in crucial care could lead to complications, such as amputations, or even fatalities that faster clinical care might have avoided. Leaving a tourniquet on too long, for example, can cause lasting nerve damage.

Jackie said a friend of his was wounded by shrapnel but couldn't leave his trench near the eastern city of Bakhmut for four days. His wounded leg became infected and ultimately had to be cut off.

Jackie thought the injury would have been an "easy fix" if the friend had received care in the golden hour. "We don't have a field medic up there pushing antibiotics through IVs, right under direct fire in a trench," he said.

Separately, a Ukrainian drone operator said that when he and his fellow soldiers were attacked by drones, one of his friends had to wait 12 hours before he could get proper medical treatment. One of the friend's legs later had to be amputated.

Drones give rise to 'magic hour' evacuations

In the cult-classic sci-fi film "Reign of Fire," "magic hour" occurs at dusk and dawn; it's the time of day when the dragons, deadly airborne dangers, are vulnerable. Tango said medics operating in Ukraine could find a similar respite at those times.

"That's when they're switching out their surveillance drones from normal analog video to either thermal or night vision," he said. "You have that limited window to move people."

Tango said, "You can't move during the daytime, or you'll get wrecked by drones." And the night has its own drone terrors.

Fighting typically slows at dawn and dusk as soldiers rest and swap equipment, though the Russians sometimes use artillery to suppress the Ukrainians during this period. A soldier hit outside this time typically must wait hours for an evacuation.

Once they can be moved, injured soldiers are typically taken back to a casualty collection point, like an underground bunker or concealed position, to be stabilized until it is safe for a truck or armored vehicle to take them to a field hospital.

What it means for the West

Drones have been used more in the war in Ukraine than in any other conflict in history, limiting battlefield movement. And the proliferation of sophisticated air defenses has prevented either side — Ukraine or Russia — from achieving air supremacy or even superiority. That makes it too risky for helicopters to rapidly pick up the wounded, as was standard in the US wars in Iraq and Afghanistan.

Recalling his Iraq deployment a decade ago, Tango said, "I knew even if I got really messed up, there is a pretty good chance I'm going to survive." He said that he "could get wrecked and probably be at a hospital within an hour or two."

In Ukraine, he said, "it's a gamble every time you step off on a mission."

The US could face similar obstacles in the event of a large-scale conflict against an adversary like China or Russia.

US Army Col. Matthew Fandre, then the senior medical officer for the Mission Command Training Program, wrote in 2020 that in a future large-scale war involving the US, the "golden hour will become a goal, not an expectation."

"This is not a paradigm shift; instead, it would be a return to the patterns and expectations of World War II operations and Cold War planning, exacerbated by current technology and lethality," Fandre wrote.

He said that without air superiority, aerial evacuations could become limited, leaving ground evacuations as the primary method. But ground evacuations would most likely also have limits, he wrote, which could "dramatically increase died-of-wounds rates."

George Barros, a conflict analyst at the US-based Institute for the Study of War, told BI that America and its allies needed a "tremendous amount of learning" to help "prepare to deter and, if necessary, defeat modern state peer adversaries like China and Russia." But there are also lessons from US experiences for Ukraine.

The US special-operations community has experience in prolonged battlefield combat care, something medics like Tango are increasingly studying and applying in Ukraine. Expanding that to the military on a large scale could be challenging, though. Troops are also considering drone deliveries of supplies into contested battlespaces, but that capability is still in the early stages.

Until then, many soldiers will continue to fight the clock after injuries, hoping for breaks in the fighting that make lifesaving treatments more accessible.

• A Jeju Air plane crashed in South Korea, killing 179 of 181 on board.
• Investigators are considering the role of a bird strike in the crash.
• Bird strikes have not caused many plane losses, and experts say it may not be the only factor.

Bird strike is being considered as a possible cause of the plane crash in South Korea, which killed almost everyone on board.

Although colliding with birds has always been a risk of flying, it has brought down comparatively few modern aircraft.

Some experts said of the Sunday crash that a bird strike was unlikely to be the sole cause.

"A bird strike should be a survivable event," said Sonya Brown, an aerospace-design lecturer at the University of New South Wales, in an interview with The Guardian.

She said that planes are designed to cope with bird strikes. Engine-builders have long tested their designs by launching bird carcasses into running engines to ensure they keep working, as reported by this CNBC article from 2017.

A June report by the US Federal Aviation Administration said wildlife strikes on civilian and military aircraft have killed 491 people and destroyed some 350 aircraft globally between 1988 and 2023.

It said that in the US, 49 civil aircraft were lost because of birds in the period between 1990 and 2023.

Civil aircraft include both airliners and general aviation planes. The latter are more susceptible to damage because many are smaller, have less robust airframes, and single engines.

While that may sound a lot, it represents a tiny fraction of total losses over that period of more than 30 years.

There were more than 27,000 aircraft fatalities between 1988 and 2021, according to the Aviation Safety Network, putting bird strikes as a factor in fewer than 1.8% of deaths. Most of the deaths involve general aviation planes.

Bird strikes on passenger jetliners very rarely bring down an aircraft. The last time it happened in the US was the 2009 crash-landing of the "Miracle on the Hudson", where everyone survived.

Most of the time, bird strikes will cause damage to airlines, but pilots are safely able to land the plane. American Airlines, for example, suffered a bird strike over New York in December and circled back to the airport for an emergency landing, with no reported injuries.

The Jeju crash reason is still unknown

Investigators have yet to give a reason for the loss of the Jeju Air flight, a Boeing 737-800.

An official in South Korea's transport ministry official said the airport's control tower issued a bird strike warning before the crash, Reuters reported.

The fire chief at Muan International Airport, where the plane crashed, said in a televised briefing that an investigation will consider whether birds stuck the plane.

South Korea's acting president ordered an emergency inspection of the country's airline operations. And the government said it will audit all 101 of the country's 737-800s with US investigators.

But a bird strike is being considered as a cause, or a possible factor. And other issues have been reported, too.

Video footage showed that the plane landed without its landing gear deployed.

Keith Tonkin, the managing director of Aviation Projects, an aviation consulting company in Australia, previously told BI: "It appears that the aircraft wasn't configured for a normal landing — the landing gear wasn't down, and it looks like the wing flaps weren't extended either."

Commentators have also pointed to the design of the airport — the plane came to a hard stop when it hit a solid wall near the runway.

Jeff Guzzetti, a former accident investigator at the US's Federal Aviation Administration and National Transportation Safety Board, told The New York Times that plane crashes are typically the result of multiple factors at once.

This is known as the "Swiss Cheese Model" in aviation, a theory that says a string of multiple smaller errors often lead to an air accident.

"The aviation industry is built on redundancy, and there are very few single-point failures in airplane design or airplane operations," he said. "Typically, it's a combination of factors."

• Europe is worried that Russia could attack countries beyond Ukraine.
• At the same time, Trump has suggested the US would be less involved in helping its NATO allies.
• Without US support, Europe lacks a key capability needed in a conflict with Russia, experts told BI.

If President-elect Donald Trump cuts US military cooperation with Europe, its NATO allies there would lose a key capability needed to resist Russian aggression.

Europe relies heavily on the US for the use of aircraft and weaponry to target air defense systems, known as suppression of enemy air defenses, or SEAD.

If a military can't execute this critical mission, its aircraft are hindered and vulnerable, unable to strike or protect, leaving its ground forces much more exposed and less effective.

"One of the most crucial things that Europe is lacking is SEAD," Tim Robinson, a military aviation specialist at the UK's Royal Aeronautical Society, told BI. He described SEAD as "a crucial role," but one Europe has let "wither the vine."

Reliance on the US

There are few dedicated SEAD platforms on the continent. Germany and Italy's Tornado aircraft carry the AGM-88 HARM munition for targeting radars and are equipped with the needed Emitter Location System, but those are set to be retired next year.

Other NATO partners operate F-16s, which can have a SEAD role, but only US Air Force Fighting Falcons are equipped with the HARM Targeting System for better SEAD.

US allies in Europe are increasingly looking to replace older aircraft with F-35s, but only a few are also acquiring AGM-88 missiles.

(These missiles are highly capable for SEAD missions and were delivered to the Ukrainian air force for this purpose, but less so for the destruction of enemy air defenses, or DEAD, missions.)

"The F-35 was designed specifically to be able to operate against modern SAM systems in both the penetrating strike and SEAD/DEAD roles," Justin Bronk, an air power expert at the Royal United Services Institute, wrote early last year.

He highlighted the fifth-generation jet's advanced stealth, electronic warfare, and active and passive sensor suite for detecting enemy surface-to-air missile systems.

"Despite these very impressive capabilities, simply fielding the F-35 is not sufficient as an answer to European NATO's SEAD/ DEAD problem in itself," he said.

This situation has left Europe heavily dependent on the US, less than ideal amid questions about US reliability and as Russia's war in Ukraine has shown how important defeating enemy air-defense batteries is in modern conflict.

In Ukraine, neither side has been able to conduct successful SEAD operations, leaving both air forces hugely hampered and forcing ground units into grinding battles with heavy casualties.

Mattias Eken, a missile defense expert at the RAND Corporation, said an important lesson from the Ukraine war has been that "air forces must be able to find, suppress, and destroy" mobile surface-to-air missiles to achieve air superiority "against even moderately equipped state opponents."

Eken added that no other Western air force except the US has significant SEAD capabilities. All other NATO forces "have limited penetrating assets, munitions stocks, and experience in operating large, mixed strike packages."

American SEAD might and a lack of European capability

Retired US Army Maj. Gen. Gordon "Skip" Davis, who served as NATO's deputy assistant secretary-general for its defense-investment division, said "the vast majority of the SEAD aircraft, in the event of aggression, would be provided by the US."

Davis told BI that the US has the stealth aircraft, including penetrating bombers, needed to locate and destroy Russian air defenses, and US aircraft have intelligence capabilities "that NATO would have great difficulty in replacing."

He warned that without better SEAD capabilities or US support, NATO "would be hard-pressed to be effective in a large Russian aggression."

Warfare experts at the US Center for Strategic and International Studies wrote in April 2023 that "NATO is now wholly dependent on the United States for SEAD capabilities."

A key example was the large-scale NATO air campaign over Libya in 2011, where the US provided almost all of the alliance's SEAD capabilities despite having planned to only play a supporting role in that situation.

Looking ahead, Europe may not be able to count on the US. Trump has been a strong critic of NATO and, in his first term, threatened to withdraw from the military alliance if other nations didn't spend more on their defense.

European countries have dramatically increased their defense spending since Russia's invasion of Ukraine began, and some now spend more on defense than the US as a percentage of GDP. (Warfare experts say that's a response to Russian aggression, not Trump's pressure.)

But Europe is acutely aware of Trump's threats, and military experts warn that the continent's increased expenditure is not enough to support Ukraine and prepare for Russia's threats alone. It still needs the US.

Thinking about the Russian threat

Russia has repeatedly threatened to attack elsewhere in Europe, and many countries have warned that it could happen in the next few years, especially if Moscow emerges victorious in Ukraine.

It's unclear if the US would or even could withdraw its support, especially for allies who already spend a lot on defense.

US forces are now so integrated in Europe that, if something happens soon, "they're automatically involved" unless the US makes a major policy shift to return forces to the US, Gordon said.

Europe is nevertheless taking actions to address its deficiencies, like a pan-European defense company now developing a new SPEAR-EW missile.

"I think the penny has dropped," said Robinson, but he added that not enough was happening. "It's taking time, I think, for European capitals and maybe multinational organizations to get the momentum going."

Michael Bohnert, a warfare expert at the RAND Corporation, said that it could take years to reconstitute a supply chain for necessary missiles. That means "there really aren't any good options" to cover a deficit in the short term if the US pulls back, he told BI.

Robinson said Europe has an advanced industrial base, but "the difficulty is it's all fragmented."

Some cooperation has taken place, including four European nations agreeing to operate their jets as a single fleet.

Jan Kallberg, a senior fellow at the Center for European Policy Analysis and a fellow at the Army Cyber Institute at West Point, said "acquisition, cooperation, and collaboration are essential."

He said countries should buy assets together and "operate jointly as a multinational force," especially given how large Europe is and how much land may need to be defended.

Fixing Europe's SEAD deficits will take time, during which it will be more vulnerable to attacks. But Russia has demonstrated an inability to effectively use its own assets — a flaw that could ultimately aid Europe.

"Europe will lack enough SEAD capabilities for the next 10 to 15 years," said Kallberg, but "the Russian air force and air defenses can't get their intelligence, command, and control to act together, and lack resources for broad modernization."

"If there is a war," he said, "it is not Europe's abilities that save the day. It is the Russian inability."

• North Korean forces are being sent forward in "human waves" against Ukraine, the White House said.
• A spokesperson said the tactic has resulted in heavy casualties, with more than 1,000 killed or wounded in the past week.
• The North Korean troops are treated as expendable and sent on "hopeless" assaults, they said.

North Korean forces are suffering heavy casualties as they carry out "human wave" attacks against Ukrainian troops, a White House spokesperson has said.

White House National Security Council spokesperson John Kirby said on Friday that the US now assesses North Korean soldiers are carrying out "massed, dismounted assaults" against Ukrainian forces in Russia's Kursk region.

"And these human wave tactics that we're seeing haven't really been all that effective," Kirby said. "We assess that they've resulted in heavy casualties for these North Korean forces."

"Our estimate is that, to date, they have suffered more than 1,000 killed or wounded in this particular fighting in just the past week of them fighting on the front lines."

Kirby said it was "clear" that Russian and North Korean military leaders saw the troops as "expendable" and were "ordering them on hopeless assaults against Ukrainian defenses."

He added that the soldiers "appear to be highly indoctrinated, pushing attacks even when it is clear that those attacks are futile."

North Korean troops first arrived in Russia in October. Ukraine said in November that it had for the first time attacked North Korean forces in Kursk, where Ukraine advanced into in August as part of its fightback against Russia's invasion.

Pyongyang's losses have since mounted, according to South Korean and Western intelligence.

Ukrainian President Volodymyr Zelenskyy said this week that preliminary estimates suggested that over 3,000 North Korean soldiers had been killed or wounded in Kursk.

North Korea's military is one of the biggest in the world, but it has little battle experience. South Korea's National Intelligence Service (NIS) reportedly said that some of Pyongyang's troops are ill-prepared for drone attacks and the terrain in Kursk.

Ukrainian officials and soldiers have said some North Korean troops have been killed by drones that they did not realize were dangerous, while Ukrainian intelligence said others accidentally killed eight Russian soldiers in Kursk in a "friendly fire" incident caused by a language barrier.

Warfare experts told Business Insider that North Korean troops appeared to be suffering high casualties as they were not given much training but that the troops could learn to adapt to the battlefield.

The NIS warned that North Korea nevertheless appeared to be preparing to put more troops in Russia, The New York Times reported.

Kirby also said on Friday that the US has reports "of North Korean soldiers taking their own lives rather than surrendering to Ukrainian forces, likely out of fear of reprisal against their families in North Korea in the event that they're captured."

The alleged treatment of North Korean soldiers is not dissimilar to how Moscow has treated some of its own forces — Russian troops have also frequently attempted to overwhelm Ukrainian positions with "meat wave" attacks.

Moving forward, Kirby said the US would remain "absolutely committed" to bolstering Ukrainian air defenses, citing Russia's Christmas attacks on Ukraine's energy infrastructure.

"No doubt this was all about weaponizing winter and weaponizing energy, making it harder for the Ukrainian people to get the heat that they need simply to subsist," Kirby said.

He added that the US would soon have another security assistance package for Ukraine, including air defense systems and gear "to help them in fighting in and around Kursk to beat back these North Korean waves, as well as continue their defensive operations against the Russians in the east."

It comes at a crucial moment for Kyiv as it gears up for the return of Donald Trump to the White House.

• Azerbaijani President Ilham Aliyev said the Azerbaijan Airlines plane crashed because of shots fired from Russian territory.
• Russian President Vladimir Putin previously apologized to Azerbaijan for the fatal crash.
• Putin did not take responsibility, however.

Azerbaijan's president said that shooting from Russian territory caused the Azerbaijan Airlines plane crash that killed 38 people.

His comments come after Russian President Vladimir Putin apologized for the incident without taking responsibility.

Ilham Aliyev said on Azerbaijani television Sunday that he didn't believe the incident was intentional but that the aircraft was hit "from the outside."

He said, per Sky News, that the fuselage was "riddled with holes," indicating that the theory the plane hit a flock of birds before crashing was incorrect.

Aliyev added that "some circles in Russia" supported this theory, while Russian officials also suggested a gas cylinder exploded on board the plane.

"In other words, this clearly showed that the Russian side wanted to cover up the issue, which, of course, is unbecoming of anyone," he said.

Aliyev went on to criticize Russia for not responding to the crash immediately, "except for some absurd theories."

According to Azerbaijani reports, the downing of the plane was connected to Russia's interception of Ukrainian drones near its border.

On Saturday, the Kremlin said Putin apologized for the crash during a phone call with Aliyev. Putin stopped short of claiming responsibility.

The Kremlin's press office said that Putin had "offered his apologies that the tragic incident had occurred in Russia's airspace and once again conveyed his deep and sincere condolences to the families of the plane crash victims and wished those injured the quickest recovery," per Russia's Tass news agency.

38 people died and 29 survived the Azerbaijan Airlines crash on Wednesday

Azerbaijan Airlines flight Flight 8243 crash-landed in Kazakhstan on Wednesday. Kazakh authorities said 38 people died, including the pilots, while 29 others survived.

The aircraft was traveling to Grozny, the regional capital of the Russian republic of Chechnya, from Baku, Azerbaijan's capital, before it diverted to Kazakhstan.

Putin said that Ukrainian drones and Russian air defenses were operating around Grozny as the plane attempted to land, Tass reported.

White House national security spokesperson John Kirby said on Friday that the US had "seen some early indications that would certainly point to the possibility that this jet was brought down by Russian air defense systems."

When questioned by media whether the US had seen intelligence that pointed to the involvement of an air defense system, Kirby said the short answer was "yes" but said he would "leave it at that."

Experts and reports have also pointed to Russia likely being behind the crash. Alleged evidence includes the erratic route the plane took as well as photo and video evidence of the aircraft that shows holes in its fuselage and tail while it was still in the air.

Rashan Nabiyev, Azerbaijan's minister of digital development and transportation, told the country's media that "preliminary conclusions by experts point at external impact," the AP reported.

"The type of weapon used in the impact will be determined during the probe," he added.

The Kremlin had initially refused to comment on the allegations.

Kremlin spokesman Dmitry Peskov said on Thursday: "Currently an investigation is in progress. Any air incident should be investigated by specialized aviation authorities."

"It would be wrong to build any hypotheses before the panel of inquiry presents its conclusions," he added.

• The US said it has "early indications" that suggest Russian air defenses downed a passenger plane.
• An Azerbaijan Airlines plane crashed while trying to land after diverting to Kazakhstan, killing 38.
• Experts pointed to damage to the plane before it landed, suggesting it had been hit by a missile.

A White House official said the US has seen "early indications" that the fatal crash of an Azerbaijan Airlines plane was caused by a Russian air defense system.

White House national security spokesperson John Kirby said on Friday that the US has "seen some early indications that would certainly point to the possibility that this jet was brought down by Russian air defense systems."

Kirby did not provide further details, but he said Kazakhstan and Azerbaijan were investigating the incident and that the US had offered to assist if needed.

When pressed for more information on whether the US had seen intelligence that pointed to the involvement of an air defense system, Kirby said the short answer was "yes" but that he would "leave it at that."

The Azerbaijan Airlines Embraer 190 plane was en route to Grozny, the regional capital of the Russian republic of Chechnya, from Baku, Azerbaijan's capital, on Wednesday.

Flight 8243 then changed course over Russia and was trying to reach Kazakhstan's Aktau airport when it crash-landed.

Kazakh authorities said 38 people died, including the pilots, and 29 others survived.

The airline's president praised the pilots' "heroism" and said the crew's dedication to their duties and prioritization of human life had "immortalized their names in history."

Russian air defenses have been active around Grozny as Ukrainian drones have targeted the area as part of Ukraine's fightback against Russia's invasion.

Multiple experts and reports have pointed to Russia likely being behind the crash, citing the plane's erratic route as well as photo and video evidence of the aircraft that show holes in its fuselage and tail while it was still in the air.

Oliver Alexander, an OSINT analyst, said in a message to BI that "at this point, I don't think there is enough available evidence to conclusively say what exactly happened (type of missile etc)."

But he said "all the evidence I have seen points to the aircraft being hit by shrapnel from an air defense missile which severely damaged the elevator and rudder controls."

Sources with knowledge of Azerbaijan's investigation told The Wall Street Journal that Russia had redirected the aircraft from its airspace and jammed its GPS system.

Azerbaijani sources with knowledge of the country's inquiry also told The New York Times that Azerbaijani officials believed a Russian Pantsir-S air defense system had damaged the aircraft.

Rashan Nabiyev, Azerbaijan's minister of digital development and transportation, told the country's media that "preliminary conclusions by experts point at external impact," the AP reported.

"The type of weapon used in the impact will be determined during the probe," he added.

Azerbaijan Airlines said on Friday that a preliminary inquiry had blamed both "physical and technical external interference" but did not give any details.

Multiple airlines said after the crash that they would suspend flights to Russia and avoid Russian airspace. Most Western airlines have already been doing so since the beginning of Russia's invasion of Ukraine in February 2022.

The Kremlin has refused to comment on reports that Russian weaponry caused the crash.

Speaking at a news briefing on Thursday, Kremlin spokesman Dmitry Peskov said: "Currently an investigation is in progress. Any air incident should be investigated by specialized aviation authorities."

"It would be wrong to build any hypotheses before the panel of inquiry presents its conclusions. Of course, we cannot do that. No one should do it," he added.

Russia's civil aviation authority pointed to a bird strike as a possible cause of the crash.

After a missile system shot down a Malaysia Airlines passenger jet in 2014, international investigators concluded that Russian President Vladimir Putin had likely given the system to separatists who used it.

All 298 people who were on board flight MH17 were killed.

• More than 100 elite North Korean troops were killed in their first battles in Russia, per South Korean intel.
• About 1,000 more were wounded in the fighting, South Korea's National Intelligence Service said.
• The troops are ill-prepared for drone attacks and the local terrain, the agency added.

More than 100 of North Korea's best "Storm" troops have been killed and 1,000 more injured fighting alongside Russia in its invasion of Ukraine, South Korean intelligence said.

South Korea's National Intelligence Service told lawmakers on Thursday that the troops' losses came in their first battles for Russia, The New York Times reported.

Lee Seong-kweun, a South Korean lawmaker, also told reporters that a general-ranking officer could be among the dead, the report said.

North Korean troops arrived in Russia in October. Ukraine said the following month that it attacked North Korean forces for the first time.

Since then, North Korean troop losses have mounted. On Monday, Ukrainian President Volodymyr Zelenskyy said that based on preliminary estimates, over 3,000 North Korean soldiers had been killed or wounded in Russia's Kursk region.

North Korean troops are primarily fighting in that region, where Ukraine launched an offensive in August.

North Korea's Storm Corps are among the most well-trained in Pyongyang's military, as well as the most indoctrinated, the Times reported.

Despite that elite status, they were still not ready for the fight in Ukraine, South Korea's National Intelligence Service said.

The agency told lawmakers that they were poorly prepared for drone attacks and the local terrain.

It's not the first time reports have suggested North Korea's forces are ill-prepared for the war.

The BBC reported that the Storm troops get more advanced training than other soldiers, but they're still underfed and some appear malnourished.

Ukrainian officials and soldiers have also said that North Korean troops have been killed by drones that they did not realize were dangerous.

Ukrainian intelligence previously reported that North Korean troops accidentally killed eight Russian soldiers in Kursk, describing it as a "friendly fire" incident caused by a language barrier.

South Korea's National Intelligence Service told lawmakers that North Korean troops were sent to Russia so quickly that Moscow could not properly integrate them into the military. They only learned a few military phrases in Russian, such as "open fire," "artillery," and "in position," before being sent to battle.

But warfare experts warn that the troops' potential impact should not be dismissed, especially given that Russia's tactics have been to use poorly trained soldiers to overwhelm Ukraine.

For its part, Ukraine is reportedly trying to get North Korean troops to surrender, making videos and dropping leaflets on troops in a bid to get them to desert. It has also warned that Russia will treat North Korean troops like disposable cannon fodder, as it appears to have done with many of its own troops.

However, South Korea's National Intelligence Service said that North Korea appeared to be preparing to put more troops in Russia, the Times reported.

Zelenskyy also predicted that North Korean soldiers would be sent to the front lines in Ukraine at some point.

• American Airlines briefly grounded all its US flights over a technical issue on Tuesday morning.
• The airline told BI that a "vendor technology issue" had affected its flights.
• Certain cancellations and delays trigger compensation under new federal rules.

American Airlines grounded all of its flights across the US for about an hour on Tuesday, saying it was experiencing technical issues.

Later Tuesday morning, American flights were back in the air. It was unclear whether the delays would reverberate through its network and cause additional issues on a big travel day ahead of Christmas.

Data from aviation analytics company Cirium and shared with Business Insider showed that only around 37% of American's flights are running on time as of 2 p.m. Eastern Time. Still, less than 1% have been canceled.

"Based on previous such incidents, it appears American has been able to maintain its schedule, albeit with delays," Cirium said in a statement.

Cancelations could grow, Cirium said, if crews "time out" — or run out of time they're allowed to fly by regulations.

Under new Department of Transportation guidelines, some passengers could be entitled to compensation if their flights are delayed or canceled.

The Federal Aviation Administration said in an advisory statement early on Tuesday that the airline's flights across the US were grounded. An update about an hour later said the nationwide ground stop was canceled.

American Airlines told BI in a statement that a "vendor technology issue briefly affected flights." That issue has been resolved, and flights have resumed.

"We sincerely apologize to our customers for the inconvenience this morning," American said. "It's all hands on deck as our team is working diligently to get customers where they need to go as quickly as possible."

The airline said the technology issue affected the systems needed to release flights, and the ground stop lasted about an hour.

Bloomberg described online posts as saying the issue prevented the airline from calculating weight and balance requirements for its flights.

More than 2,400 flight delays on Christmas Eve

The Cirium data shows that 63% of American's 3,900 global scheduled flights were delayed after Tuesday's ground stop. Planes were getting back in the air by mid-morning Eastern Time, with only 19 total cancellations.

Most of American's flights are running within two hours of their originally scheduled departure time, per Cirium, though some are reaching three hours or more.

FlightAware data shows American's hubs in Charlotte, North Carolina, and Dallas/Fort Worth are the most affected airports, with about 400 and 500 flight delays, respectively, as of 2:00 p.m. ET.

A weather advisory in effect in the Dallas area was further disrupting flights.

Federal rules about customer compensation

Users on X said they were made to get off their planes on Tuesday morning.

New Department of Transportation rules say customers are entitled to automatic refunds for flights that are canceled or "significantly changed," including domestic flights that arrive at least three hours later than scheduled. To receive a refund, a customer must not accept a changed booking.

Most airlines, including American, offer meal vouchers to travelers who wait three or more hours because of a delayed or canceled flight that was within the airline's control. American's technical issues would fall under that category.

Many provide hotels for an overnight delay or cancellation, as well as transportation to and from the airport. It's unclear whether American's Tuesday disruptions will spill over into Wednesday.

The disruption comes on Christmas Eve, one of the biggest travel days of the year.

The Transportation Security Administration said it expected to screen almost 40 million people through airports over the holidays, an increase of more than 6% from last year.

• A strike by Starbucks baristas is expanding, their union said.
• The strike is due to expand to more than 300 locations on Tuesday, it said.
• The strike began over what the union previously told BI were issues over pay and unresolved cases related to labor disputes.

A strike by Starbucks workers will expand to more than 300 locations on Tuesday, a union that represents the company's baristas said.

Starbucks Workers United said on Monday that walkouts by workers would reach new locations like Atlanta and Buffalo, as well as other locations that had not been announced, The Washington Post reported.

That means some stores in the US's largest coffee chain will be affected on Christmas Eve.

Starbucks workers began striking on Friday over what the union previously told BI were issues over pay and unresolved cases related to labor disputes.

The union said on social media that the company proposed no new wage increases for union baristas and had backtracked on a path it had agreed to with workers regarding collective bargaining and pay organizing.

"The company says they have world-class benefits and pay, but for many workers, that's not the reality," it said. "Starbucks workers often struggle to get hours to qualify for benefits, and annual raises don't match the rate of inflation."

It asked people: "While we're on strike, support workers by NOT buying from Starbucks."

More than 60 locations have temporarily shuttered because of the strikes, the Post reported.

Philly Workers United, a food service workers union, said on X on Monday that five union Starbucks locations across Philadelphia had closed the day before.

Baristas have also gone on strike in locations including Los Angeles, Chicago, Seattle, Columbus, Denver, and Pittsburgh, as BI previously reported.

The union has also shared footage of workers striking in Texas, Massachusetts, New York, and Oregon.

The union said on X that the strike would "escalate each day through Christmas Eve... unless Starbucks honors our commitment to work towards a foundational framework."

The Washington Post reported that baristas are expected to return to their jobs on Christmas or the following day.

It is not clear if strikes will later resume.

A Starbucks spokesperson told BI earlier this week that the company "offers a competitive average pay of over $18 per hour, and best-in-class benefits."

They said the company also offered competitive benefits, including "health care, free college tuition, paid family leave, and company stock grants."

The spokesperson said that "no other retailer offers this kind of comprehensive pay and benefits package."

"Workers United proposals call for an immediate increase in the minimum wage of hourly partners by 64%, and by 77% over the life of a three-year contract. This is not sustainable," they added.

The company also said in a public statement that union delegates "prematurely ended" the bargaining session this week and that it was "disappointing they didn't return to the table given the progress we've made to date."

The company wrote, "We are ready to continue negotiations to reach agreements. We need the union to return to the table."

Shay Mannik, a striking barista in Denver who has worked at Starbucks for two years, told Business Insider, "We've been in contract negotiations with Starbucks for several months now, and things have been going smoothly up until this point — when they have now refused to offer us a viable economic package."

"They just have not been offering us anywhere close to a living wage."

Starbucks has 11,161 self-operated stores and 7,263 licensed stores in North America, BI previously reported, making stores with striking workers a small percentage.

But the union said it was still the largest ever strike against Starbucks.

The union said last week that an "overwhelming" 98% of union partners had voted in favor of the strike authorization.

In a recent post on X, the union wrote: "Starbucks CEO Brian Niccol makes ~$50,000 an HOUR and commutes to work via private jet."

"All while baristas nationwide are struggling to pay their rent and get the hours they need to qualify for benefits," it added.

Brian Niccol became CEO of the company in September and has spoken about wanting to improve conditions for the company's baristas.

He recently announced a new parental leave policy for employees in the US, which is due to increase paid leave for parents from March. It applies to store employees averaging at least 20 hours of work a week.

• Cholocate brand Cadbury has lost its royal warrant, which signified its use by the royal family.
• Cadbury was awarded its warrant by Queen Victoria in 1854 and held it for 170 years.
• The brand has been owned by US company Mondelez since 2010.

Cadbury, a storied chocolate maker, has lost its royal warrant from the British monarchy for the first time in 170 years.

The warrant, which symbolizes that a company supplies goods or services to the royal family, was initially awarded by Queen Victoria in 1854.

But Cadbury was absent from the list that was updated by The Royal Warrant Holders Association this month.

The company had held its warrant uninterrupted for 170 years, according to The Telegraph.

The chocolate maker has a long history and huge popularity in the UK. According to trade publication The Grocer, its Dairy Milk was the most popular chocolate brand in the UK in 2024.

MailOnline reported that companies that didn't have their warrants renewed were notified by letters, but that, per protocol, the letters didn't give a reason.

Cadbury was bought by US conglomerate Kraft in 2010, with Kraft's food division later becoming Mondelez.

The Royal Warrant Holders Association said on its website that businesses can apply for a warrant if they have regularly supplied goods and services to the Royal Household for at least five of the last seven years and meet other criteria, such as sustainability.

It said companies can lose their warrant if their products or services are no longer made, orders have fallen, the company has gone bankrupt, or if "there is a significant change in the control or ownership of the Royal Warrant-holding company."

The association added a warrant is typically granted for up to five years, and that the company is reviewed a year before its warrant is set to expire.

Mondelez and the Royal Warrant Holders Association didn't respond to a Business Insider request for comment.

But a Mondelez spokesperson told the BBC: "Whilst we are disappointed to be one of hundreds of other businesses and brands in the UK to not have a new warrant awarded, we are proud to have previously held one, and we fully respect the decision."

Brands with a royal warrant often feature the royal coat of arms on their packaging. The coat of arms shows a lion representing England and a unicorn representing Scotland holding a shield featuring symbols of other parts of the UK.

At the bottom of the shield is a description of which royal family member granted it.

Hundreds of brands risked losing their royal warrants after Queen Elizabeth II's death in September 2022.

At the time, if they wanted to keep their warrant, they had to prove that the royal family still used their products.

Food brands that still have a royal warrant as of the latest update include Nestlé UK and Heinz Foods UK, as well as chocolatiers Bendicks and Prestat.

Cadbury was founded in Birmingham, England, in 1824 and makes products that are sold around the world, including Dairy Milk, Creme Eggs, and Mini Eggs.

Some changes have taken place since the company was bought by Mondelez, including the first changes to its Dairy Milk recipe in a century.

• Trump said the US should take control of Greenland, reigniting an old position of his.
• This came shortly after he also suggested the US could take over the Panama Canal.
• In 2019, Trump said the US should buy Greenland, an idea swiftly rejected by the island and Denmark.

President-elect Donald Trump has resurfaced an old position of his, that the US should take over Greenland, just hours after also threatening to take over the Panama Canal.

Trump wrote on Truth Social on Monday that "for purposes of National Security and Freedom throughout the World, the United States of America feels that the ownership and control of Greenland is an absolute necessity."

He made the comments in a post announcing the PayPal cofounder Ken Howery as his choice for US Ambassador to Denmark.

Greenland, the world's largest island, is an autonomous dependent territory of Denmark, which is a US ally and NATO member.

Trump's pronouncement came just hours after he threatened to take control of the Panama Canal, the man-made waterway connecting the Atlantic and Pacific Oceans.

Trump wrote on Truth Social on Monday that "the fees being charged by Panama are ridiculous, especially knowing the extraordinary generosity that has been bestowed to Panama by the US."

He added, "This complete 'rip-off' of our Country will immediately stop."

In a separate post, Trump wrote: "If the principles, both moral and legal, of this magnanimous gesture of giving are not followed, then we will demand that the Panama Canal be returned to us, in full, and without question."

"To the Officials of Panama, please be guided accordingly!" he added.

The US transferred control of the canal to the Panama Canal Authority in 1999 under a treaty signed in 1977 by President Jimmy Carter.

Panama charges fees for each vessel going through the canal, making it an important economic driver for the country.

Greenland, too, has strategic value. In addition to its own natural resources, it has proximity to the Arctic, where countries such as Russia are vying to gain resources and control.

Trump expressed an interest in the US buying Greenland in 2019, during his first term in office. Greenland's government quickly rejected the idea, saying that it wasn't for sale.

• Ukraine said it stopped a Russian spy group gathering information on its F-16 fighter jets.
• The group wanted to find out details on the airfields F-16s may be using, it said.
• Ukraine said the group's leader was detained and other members indicted.

Ukraine said it disrupted a Russian spy ring that was collecting information on the F-16 fighter jets it was given by its Western allies.

The Security Service of Ukraine, or SBU, said on Tuesday that it had neutralized a network of Russian spies that was gathering information about military targets, including its F-16s.

According to the SBU, the group was tasked with trying to discover the locations of military airfields where F-16 fighter jets might be kept, as well as the locations of Ukraine's air-defense systems and companies that make electronic warfare systems to counter Russian drones.

It said the group was working across five regions in Ukraine and was deployed by Russia's Main Intelligence Directorate, or GRU.

It is not clear how much information, if any, the group was able to gather.

The SBU said its operation exposed 12 Russian agents and their informants.

Some of them were deserters who had left Ukraine's military and were recruited by Russia while hiding from punishment, it said, adding that they used their contacts, like Ukrainian soldiers in front-line areas, to try to gather intelligence.

Ukraine's Prosecutor's Office said one deceitfully recruited three soldiers he knew by pretending to work for Ukrainian intelligence, Pravda reported.

The SBU said agents who received the information would then go to the area of potential targets to gather extra intelligence.

According to Radio Free Europe, the group's organizer was detained and prominent members were indicted on charges related to state treason and the unauthorized disclosure of military information about the movement and location of Ukrainian forces.

Other members of the group could also face charges, the report said.

The SBU said suspects could face sentences ranging from eight years to life in prison, with their property confiscated.

The F-16s are the most powerful jets in Ukraine's arsenal, making them a major military and propaganda target for Russia.

Ukraine began receiving F-16s this summer, after repeated requests for the planes. Air warfare experts say the jets are a major boost to Ukraine's defenses, helping it protect cities and other targets from Russian drone and missile attacks.

Russia began targeting Ukrainian bases where F-16s could be kept before the first ones arrived, but there have been no reports of it successfully hitting bases when the jets have been present.

Despite their perceived importance, experts say Ukraine is not receiving enough F-16s to make a major difference, and it can't use them to launch raids or go on the attack unless it gets more.

The F-16s being given to Ukraine are also decades old — and are less powerful than Russia's best jets and the most advanced planes deployed by Ukraine's allies.

• Taiwan has received 38 Abrams tanks from the US, with more tanks to come.
• It was Taiwan's first delivery of a new type of US tank in 30 years.
• China has stepped up its military aggression toward Taiwan, and some fear an invasion.

Taiwan has taken delivery of its first-ever Abrams tanks from the US, and its first delivery of a new type of US tank in three decades.

Taiwan's defense ministry said on Monday that the country had received 38 Abrams tanks from the US, according to AFP.

Taiwan's Ministry of National Defense shared pictures of tanks being moved on cranes, with the message: "Heavy Armors Have Arrived!"

The M1A2 Abrams is an advanced and heavy battle tank and is considered among the best tanks in the world.

Their arrival is likely to anger China, which claims Taiwan as part of its territory.

According to Taiwan's semi-official Central News Agency, the last tank delivery from the US to Taiwan began in 1994.

However, the US approved the possible sale of 108 Abrams tanks to Taiwan in 2019.

CNA reported that in addition to the 38 tanks already delivered, 42 are due to arrive next year, and 28 in 2026.

Taiwan's tank force currently consists of much older models, the Taiwan-made CM 11 Brave Tiger and US-made M60A3 tanks, according to AFP.

But Taiwan has increased spending on its military in recent years, as China has stepped up its military threats against the island.

These threats include large-scale military drills and almost daily incursions into Taiwan's air defense identification zone.

While Taiwan has boosted its defense spending, with a record budget next year of $19.74 billion, China is far larger, both as a country and as a military force.

US officials have said that China could be in a position to invade Taiwan by 2027.

But that doesn't mean any invasion would be easy.

A Chinese invasion of Taiwan would depend on seizing its ports, as BI reported earlier this month.

Chinese military journals "argue that the success or failure of an invasion of Taiwan likely would hinge on whether Chinese amphibious-landing forces are able to seize, hold, and exploit the island's large port facilities," naval analyst Ian Easton wrote in a new book published by the China Maritime Studies Institute at the US Naval War College.

Chinese analysts worry that Taiwan will turn its ports into fortresses against sea assault.

China is also closely monitoring the effects of Western sanctions on Russia in order to prepare for a possible invasion of Taiwan, The Wall Street Journal reported earlier this month, citing people familiar with the matter.

Meanwhile, Lin Jian, China's foreign ministry spokesman, urged the US on Monday to "stop arming Taiwan" and said the US should stop "supporting Taiwan independence forces," per AFP.

Taiwan's attempt "to seek independence through force and foreign help is doomed to fail," he said, adding: "China will firmly defend its national sovereignty, security and territorial integrity."

• A Russian drone and missile designer was assassinated near Moscow, reports say.
• Multiple Ukrainian media outlets reported that Ukraine was involved, citing security sources.
• One source said anyone who develops Russia's military power "is a legitimate target" for Ukraine.

A senior Russian official who worked at a company that designs drones and missiles was killed in a Ukrainian operation near Moscow, according to reports.

A source in Ukraine's security services told Ukrainian outlet Pravda that Mikhail Shatsky was assassinated in a special operation by Defence Intelligence of Ukraine, the country's military intelligence service.

A source told the Kyiv Independent that Shatsky was shot dead near Moscow in an attack that was likely orchestrated by Ukraine's military intelligence agency.

Ukraine has not taken responsibility for the attack.

Shatsky's body was reportedly found in the southeastern Moscow suburb of Kotelniki earlier this week.

According to Ukrainian outlet Hromadske, Shatsky was the deputy general director of Mars, a company that's part of Russia's state-owned nuclear agency Rosatom.

The outlet said he worked on the modernization of Russia's Kh-59 and Kh-69 guided aircraft missiles and helped develop new drones.

He also worked on introducing AI into Russian drones and spacecraft, Hromadske reported.

The Moscow Times and the Kyiv Independent both reported that Shatsky was a designer at Mars and head of software there.

A source told Kyiv Independent that Shatsky was seen as the main proponent of incorporating AI into Russian drones, aircraft, and spacecraft.

A security forces source told Hromadske that "anyone in any way involved in developing Russia's military-industrial complex and thus supporting Russian aggression against Ukraine is a legitimate target," according to a translation by The Moscow Times.

Russian drone attacks on Ukrainian cities, infrastructure, and military assets have been devastating throughout the war, and Russia has also used Kh-59 and Kh-69 cruise missiles against Ukrainian targets.

Ukraine has in the past been linked to the deaths of multiple pro-war figures but has commented on few of them, though a Ukrainian official said the country was behind the death of a Russia-backed lawmaker in a car bomb explosion in eastern Ukraine last year, in a rare response to such an event.

Ukrainian military intelligence didn't immediately respond to a request for comment from BI.

• The grinding Ukraine war has seen a rise in hit-to-kill drone interceptions of other drones.
• Kyiv and Moscow are increasingly using drones to take out enemy systems above the battlefield.
• This new tactic is pushing Ukraine to develop drones specifically for interceptor roles.

In the contested skies above Ukraine, a new kind of warfare is rapidly emerging as drones are increasingly sent on new attack missions. Their targets aren't armored vehicles or fighting positions — they are other drones.

Combat footage from the war in Ukraine has repeatedly captured these hit-to-kill intercepts in which a cheap drone slams into another unmanned aircraft. This practice is a cost-effective air-defense option that both the Ukrainians and Russians are using and intently pursuing.

Mykhailo Fedorov, Ukraine's minister for digital transformation, posted on Telegram in April that his country was on the hunt for interceptor drone solutions to shoot down Russian surveillance assets, the front-line eyes for strike drones and Russian artillery, "without wasting air defense assets."

Nataliia Kushnerska, a senior executive in Ukraine's defense industry, told Business Insider that using uncrewed systems in this way "marks the emergence of an entirely new segment of modern warfare — drone-on-drone combat."

A new tactic in the evolving drone war

Drones have dominated the battlefield throughout much of the Ukraine war, being used for land, sea, and air missions. Cheap first-person view (FPV) drones are frequently used to carry out pinpoint strikes on enemy armor and troop positions, while larger systems collect intelligence.

But as the war has dragged on, drones have increasingly been used in an air-defense role to take down enemy uncrewed aerial vehicles (UAVs) carrying out reconnaissance and attack missions. These aerial engagements can, at times, resemble the fierce dogfights of the World Wars.

An outfit that makes combat FPV drones posted in August that its modified drones had taken out 100 Russian UAVs. The Wild Hornets, as the operation calls itself, shared footage of some of the interceptions.

Kushnerska, the chief operating officer of Brave1, a Ukrainian government platform that facilitates innovation within the country's defense industry, said interceptor drones have become "one of the innovations of this war."

The tactic, she said, makes it more difficult for Russia to operate its drones deep behind the front lines and collect data to facilitate missile and drone strikes on Ukrainian positions, which has been a real challenge for Ukraine as Russia pushes to expand its reconnaissance strike complex. This also awards Kyiv more flexibility to carry out its military operations and maneuvers.

Kushnerska said Ukraine was the first to use drones to intercept Russian reconnaissance UAVs, but Moscow has since adapted to the tactic and found ways to evade the interceptors. Now, efforts are underway to improve the systems so they remain effective.

It is the latest iteration of what a senior Ukrainian official previously described to BI as a cat-and-mouse game between Kyiv and Moscow, where each side is constantly attempting to one-up the other in developing drones and other war-related technology.

Samuel Bendett, an expert on drones and Russian defense issues with the Center for Naval Analyses, told BI Moscow is similarly using FPV drones to take out Ukrainian systems and that Russia has also equipped its drones with defenses against interceptor drones, such as electronic-warfare jamming systems.

Bendett said that the Ukrainians "have gotten very successful in fielding their FPV drones against Russian ISR assets, and the Russians have gotten successful, up to a point, with using their FPV drones to go after Ukrainian heavy quadcopter UAVs."

Interceptor drones are limited in range and altitude and often carry less explosive power than more traditional air defenses like missiles. Drones provide Ukraine and Russia with an alternative way to take down aerial threats, one in which the cost of the intercept is often less than that of the system being targeted.

Kushnerska said an interceptor drone typically costs between $2,000 and $4,000. An air-defense missile, on the other hand, could cost hundreds of thousands — or even millions — of dollars. Using drones reduces dependency on more expensive munitions and frees up Ukraine's air-defense units to focus on the bigger threats like Russian aircraft and more deadly cruise and ballistic missiles.

Pursuit of more interceptor drones

For the Ukrainian soldiers tasked with intercepting Russian drones, it's a dangerous mission.

One drone operator in the Ukrainian military told BI that he operates from trench shelters very close to the front lines. He said the pilots are priority targets for Russia, which will use "every single thing at its disposal" to take them out.

The Ukrainian operator said that drone-on-drone combat is increasing. He said he sometimes uses interceptor drones up to five times a week. But Ukraine needs more of them.

Kyiv has taken steps to procure more of these interceptor drones. Last month, for instance, a Ukrainian drone engineering company announced it had completed testing for a new FPV drone designed to take down Russian reconnaissance UAVs, like the Orlan, and was ready for military use.

But there's still more to be done. Valeriy Romanenko, a former air-defense officer who's now a researcher at Ukraine's State Aviation Museum, told BI that Kyiv's interceptor drones are good for slower reconnaissance UAVs at lower altitudes.

However, he said, Kyiv ultimately needs faster interceptor drones to take down Russia's deadly attack drones, like the notorious Shahed-136. In October alone, Moscow fired around 2,000 of these systems at Ukraine, according to Western intelligence.

The Wild Hornets have been working on a new "Sting" UAV to effectively combat the Shaheds, but it's a work in progress.

This hit-to-kill intercept tactic has implications well beyond Ukraine and could be used in future conflicts, too. Mick Ryan, a retired Australian Army major general and strategist, said the use of drones for interceptions will likely be a lasting element of military operations.

"This is a trend that's here to stay unless there is some fundamental breakthrough in very low-cost anti-drone systems, and we're not seeing that at this point," he told BI. "I think this is an enduring kind of capability that many militaries should be looking at."

On April 27, 2023, Diana Kulyk's father told her he was leaving the next day to start training to fight Russia. She was filled with dread but knew she needed to act. Her hands shaking, Kulyk, a 24-year-old only child, tried to type the perfect tweet that would convince her roughly 20,000 followers to donate more than $3,000 for equipment that would help keep her father alive.

"Hello, this is the most important tweet I have ever written," she began. "I'm Diana Kulyk, daughter of Ruslan Kulyk. My father is a simple man, a baker by profession, a human being full of love and care. The person who took care of me since I came into this world. He needs help." Beneath the text were two images: a selfie of Diana and Ruslan smiling under golden-hour sunlight, and a spreadsheet of equipment she'd determined her father needed for the battlefield, including steel body armor, a tactical headset, a ballistic helmet, and a sleep mat.

Diana had already raised about $30,000 over the previous year to buy protective gear for childhood friends fighting in Ukraine. Within two hours of posting about her father, she had raised enough to buy all 21 items on the spreadsheet. The donors came from all over: Ukraine, the United States, Germany, England.

Watching the donations flood in, Diana was overwhelmed. "It was a really weird moment," she says. "You are so scared, but also you see everyone coming together to help you. It gives you hope."

Diana's efforts are part of an immense crowdfunding movement helping fuel Ukraine's fight against Russia's far larger and more advanced military. The Ukrainian government has its own crowdsourcing platforms, like United24, which has raised more than $761 million to pay for things like ambulances and demining equipment and to reconstruct destroyed buildings. Individual military units are using social media to campaign for the specific gear they need on the front lines. The 79th Separate Airborne Assault Brigade, for example, has used Instagram to gather donations for reconnaissance drones, generators, and night-vision goggles. And thousands of volunteers are raising funds to directly supply their loved ones on the battlefield with walkie-talkies, combat boots, Starlink internet satellites, medical supplies, ammunition, tanks, and phone chargers.

People have crowdfunded wars throughout history. In World War II, the Supermarine Spitfire, a British fighter aircraft, was largely financed by bake sales and fundraisers at primary schools. But never have funds been raised so easily, quickly, widely, and strategically by civilians and individual troops, says Keir Giles, a defense expert at the think tank Chatham House. "That's a big advantage," he says. With the modern tools of social media, influencer marketing tactics, crowdfunding platforms, and frontline postal services, "units can campaign for precisely the equipment and weapons they need and have them delivered."

Benjamin Jensen, a war-strategy expert at the Center for Strategic and International Studies, describes this crowdfunding as a "game changer." People around the world, he says, are directly "buying commercial off-the-shelf capability to enhance combat power on the battlefield," often acting much more nimbly than the military.

Crowdfunding is also increasingly critical. While Western nations have contributed nearly $300 billion worth of aid, Ukraine's military has repeatedly suffered from shortages of key weaponry and defense equipment. Three grueling years in, several countries and leaders are weighing whether they'll continue their support — including the United States and President-elect Donald Trump, a frequent critic of US aid to Ukraine. The Ukrainian government said last year that crowdfunding accounted for 3% of the country's total military spending. To win the war, that number may need to climb. But fundraisers are struggling with fatigue among citizen donors and are getting creative to keep up funds and morale.

Before the war, Ruslan Kulyk was a pastry chef who made wedding cakes in Spain, where the family immigrated when Diana was young. When the wedding industry slowed in the winter, he visited family in Ukraine's northeastern Sumy region. On February 24, 2022, he was preparing to return to Spain when Vladimir Putin launched Russia's full-scale invasion. Landlocked and infuriated, he joined his nephew at the military registration office. Recruiters enlisted his nephew but turned Ruslan away. "I wasn't prepared and was 50 years old," he says.

He got a job at a local bakery. He trained hard, dropping more than 50 pounds in 14 months. By the time he went back to enlist, Ukraine was thought to have lost as many as 17,500 soldiers and badly needed more men on the front lines.

After training in Kyiv, Ruslan joined a "storm" brigade, an extremely dangerous type of counteroffensive unit that often operates on the edge of Russian strongholds. Diana and Ruslan talked frequently, but his work often required him to go dark for days on end. For Diana, the wait was terrifying. She scoured the news to see where "the hottest part" of the fighting was, figuring that's where her father would be. "You wake up every day thinking I'm going to have bad news today," she says.

Being able to crowdfund equipment for her father and his fellow soldiers has given Diana a semblance of control to counter the nauseating sense of helplessness. It has also helped save lives.

In the summer of 2023, Ruslan texted his daughter, "I'm going on a mission." Four days later, he called from the hospital. He had been sent to Bakhmut, where a Russian drone had exploded 18 inches from his head, giving him and three of his comrades concussions. One was so severely injured that he had to be wrapped in a tourniquet that Diana had fundraised for. (The soldier's leg was amputated, and he's now with his family.) Diana spent a week with her father as he recovered in the hospital.

When he returned to active duty, Ruslan became a drone operator. Though he was farther from the front lines, he was arguably in even more danger. Drone operators have been very effective: Citing Ukrainian military commanders, The New York Times reported last month that Ukraine's drones accounted for at least 80% of Russian front-line losses. Several Ukrainian drone operators have told Business Insider that because of this, they are disproportionately in the enemy's crosshairs. Ruslan calls drone operators Russia's "target No. 1." This October, while in the Luhansk region, Ruslan used a surveillance drone Diana had raised funds for to spot four Russian soldiers advancing toward his unit, giving Ruslan and his comrades enough time to avert an onslaught.

Diana has raised more than $100,000 for drones, jackets, boots, helmets, medical supplies, trench-digging equipment, and thermal-vision gear. She credits part of her success to "how transparent I am with my situation, with my family." Much of her support comes from partnering with NAFO, the North Atlantic Fella Organization, an online community playing on the NATO name that challenges Russian disinformation, largely through dog memes.

Some crowdfunders encourage donations by sharing stories about themselves or their friends. Some host livestreams or ask followers to celebrate their birthday by donating to a soldier's unit. Others offer services and products: You can get a message written on ammunition to be fired at Russian targets or buy artwork made of bullets, shells, and destroyed Russian equipment and uniforms.

Dimko Zhluktenko, a 26-year-old former IT manager in Kyiv, didn't join the military at the start of the war. "I chickened out in the beginning a bit," he says, and he was taking care of his sick mother. But he knew his tech skills could allow him to help Ukraine in another way. It was obvious to him that the military wasn't getting the resources needed to win the war, so he started buying protective gear for his friends.

He posted about his efforts on X, sharing stories of his childhood friends on the front lines, like Max, who destroyed a bridge to stop a key Russian advance. His followers responded. "Many people started asking, 'How can I send you money?'" he says. By April 2022, Zhluktenko had received so many of those requests that he decided to work on fundraising full time, starting a charity organization to provide "high-tech equipment" that would increase "the efficiency of our forces." He called it Dzyga's Paw, named after his dog. Donors can get merch — like stickers, tote bags, and patches — based on how much they donate. He's raised more than $2.9 million from more than 28,000 individual donations.

Giles says that because the crowdfunding effort is so complex and unregulated, there have been "persistent allegations of fraud" against several groups. To counter that, Zhluktenko has made his organization radically transparent. On Dyzga's Paw's website, among other details about its budget, the organization keeps a daily log of its expenses. In one week in November, for example, it paid two employee salaries ($1,166.89) and bought 15 Starlink satellite receiver kits ($4,884.13), an F13-Retrik uncrewed aerial vehicle ($2,780.36), and paper clips ($0.75).

Zhluktenko is also transparent about who exactly is receiving which equipment and what they're using it for. To motivate people to donate, he constantly shares stories on social media about soldiers like Nazar, who coached a youth soccer team before the war. In a post on X in October advertising a fundraiser, Zhluktenko's organization wrote, "Nazar and his unit need essential equipment—from laptops to portable power stations and signal-boosting antennas for drones to be even more effective."

Dyzga's Paw also shares videos of frontline soldiers expressing gratitude, memes of gear en route to soldiers, and, crucially, footage of the gear donors have funded in action, often captured by drones they've also donated. Zhluktenko says these videos — often of Russian tanks being blown up or Russian soldiers surrendering — are extremely effective marketing: Donors "actually get to see the impact of the equipment they have sent" and how their donations "challenge the myth of an undefeatable Russian army."

Mats Kampshoff, a 25-year-old student in Germany, has given about $600 to Dyzga's Paw and other crowdfunding projects during the war, though he has no personal connection to Ukraine beyond the stories of soldiers he's been following. "Connecting this war effort with a daily life that I can connect to really brought home the point that I don't want this war to be around," he says. Donating feels "more like a logical decision than one based on morals," he says, adding that "it's just the small part that I can do to shape the world in the way that I envision."

In surveys of Ukrainians conducted in 2022 and 2023, almost 80% of respondents said they'd donated to some form of crowdfunding campaign during the war. Most of Zhluktenko's donors are from Europe, the US, Australia, Japan — "any countries Russia would call the collective West," he says. "There are people who have donated for 50-something weeks straight."

Hlib Fishchenko, 25, founded a volunteer organization called Vilni, which he said gets about 80% of its donations from Ukrainians. He raises money for items like excavators that help protect soldiers building trenches; the last one Vilni bought cost about $25,000, which it raised in a month. He said Ukrainian donors understand that they could donate to rebuild a school, or they could donate to help soldiers prevent Russia from destroying schools in the first place. They see their donations as preventive, he said, while some international donors are more willing to fund projects like reconstruction and medical aid.

Receiving donations for equipment is one thing. Getting the equipment to the front lines is another.

Zhluktenko's team goes on a frontline expedition about once a month. Their motto is "Just don't be stupid." In July they were driving toward Kharkiv when they learned of an imminent Russian glide-bomb attack nearby and changed their route.

Organizations and crowdfunders, including Dyzga's Paw and Diana Kulyk, often work with Nova Post, a major Ukrainian delivery company that delivers close to the front lines. Nova Post told BI that it delivers to residents and the military and that it stops only when the military "says that it is dangerous to work and forbids us to open branches." The company said that branches have indoor and outdoor shelters designed so that employees and clients can reach them within 30 seconds and that frontline branches have reinforced doors and windows.

The company's operations have only grown: It told BI it had opened 2,242 branches and two sorting offices and installed 1,853 parcel lockers since February 2022 and that it shipped 30% more parcels in 2023 than it did in 2022.

Experts say the crowdfunding of Ukraine's fight could offer a glimpse into the future of warfare. Major Western militaries are unlikely to start relying on crowdfunding anytime soon, given their extensive resources and stringent procurement policies. But Jensen, the war-strategy expert, predicts that crowdfunding via social media will be vital in "future insurgencies against authoritarian regimes." Giles says he's already seeing "more explicit calls on soldiers to equip themselves," with soldiers in countries like Latvia and Finland, which he says "may be facing Russian aggression next," buying more military equipment themselves.

Giles says this war might be unique in that it has dragged on long enough for these campaigns to develop. But it's also dragged on long enough for some support to wane. Several fundraising groups said they'd seen donations dry up in recent months; fatigue is setting in as the war concludes its third year. In November, an advisor to President Volodymyr Zelenskyy told Bloomberg that the donations he'd received that month through YouTube livestreams had plummeted by two-thirds compared with what he raised in March. The advisor also said he feared that Donald Trump's return to the presidency would further hinder donations. "Floating talks about Trump's promise to end the war quickly and possibly bring peace reduce willingness of people to donate," he said.

One thousand and sixteen days into the war, fighting rages throughout Ukraine's east. Russia controls nearly 20% of the country. While there are no confirmed death tolls and estimates vary wildly, many tens of thousands of soldiers are believed to have been killed on both sides.

Zhluktenko got married in July and then signed a military contract. "Ukraine needs people fighting," he says. "It's impossible to win a war for your freedom without fighting for your freedom." On October 23, his birthday, he posted on X: "My birthday wish this year is survival. I don't need any gifts this year except something that will help me be effective in my military role and to survive." While he's on duty, his wife has taken over Dyzga's Paw.

Diana Kulyk completed another campaign several months ago, raising $48,000 to buy her father's brigade two pickup trucks with night-vision cameras and all-terrain tires. But she says that regardless or whether her dad needs anything, she spends much of her mental energy trying to prepare herself for the possibility of her father's death. She's lost friends in the war. She lost her cousin — Ruslan's nephew, who went to the registration office with him. And she's watched her father lose comrades.

"There is a high chance of it eventually happening, so I have been working on that," she says. "I have a phrase I came up with to tell myself: 'Better to be a man of honor than to live scared.'"

• November saw Russia hit a new daily average high for its casualties in the war, per the UK MOD.
• It said the losses were "likely reflective of the higher tempo of Russian operations" against Ukraine.
• It was the third month in a row that Russia suffered record-breaking daily losses, it said.

November saw Russia suffer a record daily average for the number of soldiers injured or killed since it launched its full-scale invasion of Ukraine in 2022, according to UK intelligence.

The UK Ministry of Defence said in an intelligence update on Thursday morning that "the average daily Russian casualties (killed and wounded) in the Russia-Ukraine conflict reached a new monthly war high during November 2024."

Citing the Ukrainian General Staff, it said that Russia suffered 45,680 casualties in November, up from 41,980 in October, with a daily average of 1,523.

It was the third month in a row that Russian forces suffered record-breaking daily average losses, it said, and the fifth straight month that it had seen its total losses rise.

The increased casualty figures, the UK MOD said, are "likely reflective of the higher tempo of Russian operations and offensives."

According to the MOD, Russia is trying to increase pressure on Ukraine's lines as it tries to push it back on several fronts, notably in Kupiansk, Toretsk, Pokrovsk, and Velyka Novosilka, as well as in the Russian region of Kursk, which Ukraine partially occupied in August.

The losses likely made it the most costly month of the war for Russia in terms of personnel, it said.

The MOD added that Russia's casualties "will likely continue to average above 1,000 a day in December 2024 despite the onset of winter," with continued attacks on multiple fronts.

Russia has been relentlessly trying to push forward on multiple fronts in Ukraine over the past few months, slowly gaining territory, but in a way that warfare experts say is not proportionate to its losses.

Washington DC-based think tank the Institute for the Study of War said in an update on Tuesday that Russia suffered significant losses of people and armored vehicles last month as it "attempted to maintain intensified offensive operations in eastern Ukraine."

It also pointed to Russia's losses in September and October and said the country "cannot sustain such significant loss rates indefinitely in return for gradual, creeping battlefield gains."

George Barros, a Russia analyst at the ISW, told BI in September that Russia's death toll was rising because it had been running a high tempo of operations without really taking a substantial pause since October 2023.

"What we have seen here is a really active Russian military, which has been just sort of sprinting for a very long time and continuing to sprint," he said.

NATO Secretary General Mark Rutte said in late October that over 600,000 Russian troops had been killed or wounded in the conflict.

Russia doesn't release its own figures.

Rajan Menon, a senior research scholar at Columbia University's Saltzman Institute of War and Peace Studies, told BI that "the kind of fight the Russians have been doing is to say: 'To hell with losses, we are just going to push forward wave after wave after wave.'"

Russia's plan for victory in Ukraine, according to many warfare experts, has been to keep pushing forward with the expectation that Western support for Ukraine will fade and that Ukraine's military will become increasingly fatigued.

Such a scenario could result in Ukraine not having the weaponry it needs to fight, or for it to be pushed into a peace deal that would involve it giving territory and other concessions to Russia.

• A new NATO member has a jet that was designed for war with Russia
• But it has never been used against Russia.
• Giving Ukraine the jet would be a good test that would benefit it and NATO, warfare analysts said.

Sweden's Gripen, a fighter jet built for a war with Russia, is considered a good fit for Ukraine, but the aircraft hasn't been tested the way it could be in this war.

The conflict in Ukraine has been a test bed for weapons on both sides, from Russia's new hypersonic missiles to older systems like the American Patriots, showing their users how they perform in high-end combat. Some systems have underperformed, while others have far exceeded expectations in this tough operating environment.

Not only would giving the jets to Ukraine — which Stockholm has indicated is possible — potentially strengthen its air force, but it could also give NATO insight into how a key capability performs in a real-world combat scenario, specifically one for which it was made.

Helpful for NATO

Sweden initially refused to put its jet on the table for Ukraine, but it has slowly become more open to the idea. The defense ministry said in September that it was acquiring Gripen parts, and in late November, it was reported that those parts were being transferred to Ukraine.

It is, however, unclear if and when Ukraine could receive the actual jets. Swedish Defense Minister Pål Jonson said recently that his country has been advised to wait until Ukraine is further along in setting up its new American-made F-16 fleet. Concerns have been raised about unintentionally overloading Kyiv with new equipment.

But at some point down the road, there's the possibility Kyiv receives the Gripen, a rugged, capable fourth-generation fighter.

Designed at the end of the Cold War, the jet is operated by about half a dozen countries. It was built to fight Russia's Sukhoi fighter aircraft, but it's never been in that kind of combat.

Tim Robinson, a military aviation specialist at the UK's Royal Aeronautical Society, told BI that the aircraft was designed to fit into Sweden's vision of having a dispersed and mobile air force to counter Russia as a threat. "The idea of keeping on the move, rapid turnarounds, and being very, very hard to destroy," he said.

He said NATO would be interested in seeing how the jet performs against Russia, especially given the aircraft has "quite a good electronic warfare system," which is something that this fight has shown is necessary to defeat Russia.

Air-to-air combat is not common in Ukraine, but George Barros, a warfare expert at the Institute for the Study of War think tank, told BI that "there may be some tactical advantages that Sweden can learn from Gripen's performance against Russian planes." It could also benefit the larger NATO alliance.

Sweden joined NATO in March of this year as a result of Russia's invasion of Ukraine, and the alliance celebrated the move as one that would help it in the event of a conflict with Russia. That's due to Sweden's geographical location and because its military was built around the Russia threat.

And there are benefits for the jet's manufacturers as well. Michael Bohnert, a warfare expert at the RAND Corporation, said that Saab is in "global competition" with its rivals as countries seek fourth-generation fighters. That means Sweden — as well as France, which has offered Ukraine Mirage aircraft — "both have strong incentives to provide aircraft with high performance and support to Ukraine."

Robinson said that having a jet proven in combat is "definitely a factor when selling military aircraft."

The Gripen was used in Libya in 2011, but it was only for reconnaissance. The models that Ukraine would likely get would be the older C and D models, but if those versions were to do well in Ukraine, it could still help the sale and reputation of newer models now being produced.

Retired US Army Maj. Gen. Gordon 'Skip' Davis, who served as NATO's deputy assistant secretary-general for its Defense Investment Division, told BI the Gripen performing well in Ukraine "would be a great boost for Saab and Swedish defense industry."

He said that "if it does well in Ukraine, then it would be the selling point. But I would also tend to think that it would do well simply because the Swedes themselves have been so focused on Russia as a potential threat and enemy for quite some time."

Helpful for Ukraine

The main reason to send the jets to Ukraine, though, would be to boost its airpower. Barros said that "sending Ukraine more aircraft is a step in the right direction."

War experts have said the Gripen is the jet that is best suited for Ukraine in the long term.

Bohnert previously told BI that "Gripens are a way better fit for Ukraine" than F-16s, as they are "a little more purpose-built" for what Ukraine needs. "Sweden, being under that Russian threat, designed the Gripens to fight this way that F-16s weren't," he said.

The aircraft was designed to work from civilian roads so that it can still function if runways and airbases are destroyed; Russia has targeted that infrastructure during the war. It also requires less maintenance than some aircraft, like the F-16s, which is useful for a country actively at war.

Robinson said "it's almost perfect for Ukraine's needs in a way," but he noted that the jet has drawbacks, like there not being as many in service as F-16s, which means allies could not be as helpful with things like providing spares.

Ukraine's future may rely more on support from Europe as former US President Donald Trump set to take office next year. He has been more critical of support for Ukraine.

A challenge, Peter Layton, a fellow at the Griffith Asia Institute and a former Royal Australian Air Force officer, told BI, is that the Gripen has some US-made components, which means the Trump administration would likely have to agree to Sweden giving Ukraine Gripens if it tried to do so. For the time being, it remains uncertain if Sweden will ultimately commit the jets.

• Russia is treating the first North Koreans sent to fight alongside it well, Ukraine's president said.
• But Volodymyr Zelenskyy said this was about trying to get more of them to come to fight.
• Ultimately they will be used as "cannon fodder," he said.

Ukrainian President Volodymyr Zelenskyy said that Russia is treating the first batch of North Korean soldiers sent to aid in its war against Ukraine well, but that it won't last.

Zelenskyy told Japanese news agency Kyodo News on Sunday that Russia was treating the North Korean troops well in order to try to attract tens of thousands more.

But he predicted that the troops would at some stage be sent to the front lines and that it was "indisputable" that Russian President Vladimir Putin would ultimately use them as "cannon fodder."

Officials in the US, Ukraine, and South Korea claim that North Korea has sent thousands of troops to aid Russia.

Zelenskyy said there is evidence that about 12,000 North Korean troops have been deployed so far, and Dmytro Ponomarenko, Ukraine's ambassador to South Korea, said last month that the number of North Korean troops sent to Russia could reach 15,000, with troops rotated out every two to three months.

That could mean around 100,000 North Korean soldiers serving in Russia within a year, he said.

North Korean troops have been deployed in the Russian region of Kursk, where Ukraine made a surprise counteroffensive in August, seizing hundreds of square miles of Russian territory.

Zelenskyy said during the interview with Kyodo News that North Korean troops had been killed there, confirming previous reports.

In June, the Pentagon warned that North Korean troops would be treated poorly by Russia, in response to initial reports that North Korea was considering sending Russia some of its military personnel.

Pentagon Press Secretary Maj. Gen. Pat Ryder said at the time that "if I were North Korean military personnel management, I would be questioning my choices on sending my forces to be cannon fodder in an illegal war against Ukraine."

Russia has been accused of treating its own soldiers badly during the conflict.

Zelenskyy also warned Sunday that the use of North Korean troops during the conflict could be dangerous for Asia, since those soldiers would get trained by Russia and would get knowledge about fighting in a modern war, in areas like using drones.

Mykola Bielieskov, a research fellow at Ukraine's National Institute for Strategic Studies, told BI that even if the soldiers North Korea sends are well trained by their own standards, "I think their training still would be lacking in terms of the modern battlefield they have in the Russia-Ukraine war."

He added: "I think that it's safe to assume that they might be used as expendable infantry or just thrown as a mass of people."

Bielieskov also said that while the estimated number of up to 12,000 North Korean soldiers in Kursk right now was not huge by the standards of the war, it might be enough to make a difference against Ukraine on a single front, if that's how they are used.

Last month, South Korea's defense minister, Kim Yong-Hyun, said that North Korean troops would likely be sent to the war's hot spots.

He said that Russian officers are "likely to send the North Korean platoons to the most dangerous and difficult areas."

According to South Korean intelligence, Russia is paying about $2,000 a month for each North Korean soldier.

But North Korean military experts told BI that the soldiers themselves are not likely to see much of that, with the state likely pocketing most, if not all, of the money.
