North Korea has suffered more than 6,000 casualties during offensive operations in Russia’s Kursk Oblast, according to a June 15 report from the United Kingdom’s defense intelligence.

According to the report, North Korea's losses account for more than half of the approximately 11,000 troops initially deployed to Kursk in fall 2024.

U.K. intelligence attributed the high casualty rate to large, highly attritional dismounted assaults.

Open source intelligence reports have also suggested that small numbers of additional North Korea troops have been deployed to make up for the losses.

Earlier this year, South Korea's Joint Chiefs of Staff reported that North Korea transferred approximately 3,000 additional soldiers to Russia in January and February.

North Korea has emerged as a key military ally of Russia through its invasion of Ukraine, supplying Moscow with artillery shells, missiles, and even soldiers in exchange for oil products and advanced military technology, such as ballistic missile upgrades.

In April 2025, Russia confirmed for the first time that North Korean forces were fighting alongside Russian troops in Kursk, although North Korean troops have been reportedly involved since fall 2024.

Ukraine launched a cross-border incursion into Kursk Oblast in August 2024, marking the first large-scale invasion of Russian territory by foreign forces since World War II. The operation aimed to disrupt a planned Russian offensive on the neighboring Sumy Oblast and draw Russian forces away from the embattled Donbas region.

Russia launched a push to recapture the region in early March 2025, with Ukraine being forced to pull back from much of the initially taken territory.

Editor's Note: June 15: This article has been updated to include confirmation of the attack from Ukrainian authorities.

Ukraine allegedly launched drones at Russia’s Tatarstan region, killing one and injuring 13, regional governor Rustam Minnikhanov reported on June 15.

The Ukrainian drones were reportedly shot down, but the debris fell on a plant in the town of Yelabuga, where Russian Shahed-type attack drones are manufactured, causing a fire.

According to Minnikhanov, it was an automobile plant, but some Telegram channels, including Astra, speculate that the well-known drone factory was the target.

Ukraine's General Staff subsequently confirmed details of the strike, including that it was directed at Shahed-style drone production in Yelabuga.

“Despite the attempt to sow fear and panic, all enterprises and life support facilities in the republic are operating stably. Emergency services are on constant alert,” said Minnikhanov.

A video of the attack was shared on Telegram, showing smoke billowing over the town, which lies some 1,500 kilometers from Kyiv.  There has been no official statement from Kyiv on the alleged strike, and the Kyiv Independent could not independently verify these claims.

The so-called Alabuga Special Economic Zone hosts a factory producing Shahed-type long-range attack drones as well as other reconnaissance drones, and has been repeatedly targeted by Ukrainian forces since its launch in 2022.

The factory aims to produce 6,000 Shahed-type drones a year, with each one estimated to cost as little as $20,000.

Last year, Ukraine confirmed attacking military facilities in Tatarstan at least twice with long-distance drone strikes. Most recently, Ukrainian drones reportedly struck the plant on May 25.

Facing a workforce problem, the factory began recruiting African women under false pretences via a work-study program. As a result, Interpol began an investigation into the company in April for human trafficking.

Ukrainian actor Yuriy Felipenko, who worked with Kyiv Independent reporters, was killed at the frontline, his wife Kateryna Motrych wrote on social media on June 15.

Felipenko was well known for his role in the 2024 television series “A Promise to God” before joining the Achilles Strike Drone Battalion, then part of Ukraine’s 92nd Assault Brigade, in April 2024.

Having since been upgraded to a separate regiment and one of the founding units of the Line of Drones initiative, Achilles is one of the most effective drone units in the country.

“Yura was killed. Yura was, without exaggeration, my world, my soul, my light. It is impossible to convey this loss. I feel like I have been destroyed,” Motrych wrote on her Instagram page, accompanied by a photo of Felipenko.

Felipenko's drone team was featured in a report by the Kyiv Independent on Ukraine's use of first-person view (FPV) drones against Russian infantry assaults in December 2024 as they defended the area around Kupiansk in Kharkiv Oblast.

Details of Felipenko’s funeral will be announced later, Motrych said.

Russia has killed numerous actors, artists, and writers since the start of the full-scale invasion. Many have fallen on the battlefield while others were killed during attacks on civilian areas.

Ukraine recovered another 1,200 bodies following the latest round of repatriation efforts, following agreements with Russia in Istanbul, the Coordination Headquarters for the Treatment of Prisoners of War said on June 15.

The last repatriation took place on June 14 when the bodies of 1,200 fallen Ukrainians were given back. Before that, 2,412 bodies were returned on June 13 and June 11 respectively, following the talks in Istanbul on June 2.

Law enforcement investigations and institutions from Ukraine’s Interior Ministry will examine and identify the bodies in the near future, the coordination headquarters said. The bodies reportedly include military personnel.

The repatriation operation was coordinated by the Coordination Headquarters for the Treatment of Prisoners of War alongside the Security Service of Ukraine (SBU), the Ombudsman’s Office, the Armed Forces, the Interior Ministry, and other government and defense bodies. The International Committee of the Red Cross also provided assistance during the process.

While the Istanbul talks failed to foster a ceasefire, both sides agreed to new POW exchanges. Ukraine has long pushed for an "all-for-all"prisoner exchange to bring home all Ukrainian captives, but Moscow has resisted such a comprehensive deal.

After the talks, Russia said it would transfer 6,000 bodies to Ukraine, including soldiers and officers. Ukrainian President Volodymyr Zelensky said Ukraine would need to check the bodies that Russia is willing to return, as only 15% of the 6,000 have been identified.

"We had instances when they returned bodies that later were identified as their own," Zelensky said on June 2.

Ukraine’s military intelligence (HUR) ignited an electrical substation during a sabotage operation in the Russian city of Kaliningrad, causing $5 million in damage and cutting electricity to a military production site, a source in HUR told the Kyiv Independent.

In the early hours of June 14, Ukrainian agents drained the coolant from the substation’s power transformer before setting the facility on fire. The inferno inflicted major damage on the facility and caused a power cut, impacting nearby Russian military sites.

"We once again remind you that Russia no longer has a rear either in the east, in the west, or anywhere else on the planet. Everything Russian involved in the war against Ukraine will burn, sink, and be destroyed regardless of its level of protection or location," the source said.

Ukraine continues to carry out numerous secretive attacks within Russia and occupied Ukrainian territories, targeting military sites, like airfields, as well as key infrastructure like railways and oil refineries.

The attacks involve HUR, Ukraine’s Security Service (SBU) as well as partisan and sabotage groups.

HUR was behind explosions near Desantnaya Bay in Russia's far eastern Vladivostok on May 30, which reportedly damaged military personnel and equipment. The operations took place approximately 6,800 kilometres from the Ukrainian border, making it Ukraine's furthest incursion into Russian territory, if confirmed.

On June 1, the SBU launched Operation Spiderweb, a game-changing drone attack on four key Russian military airfields, damaging 41 planes, including heavy bombers and rare A-50 spy planes.
