North Korean troops have been killed during combat against Ukrainian forces in Russia’s Kursk border region, according Ukraine’s military intelligence agency and the Pentagon.
The deaths are the first reported since the US and Ukraine announced that North Korea had sent 10,000 to 12,000 troops to Russia to help it in the almost three-year war.
Ukraine’s military intelligence agency said about 30 North Korean troops had been killed or wounded during battle with the Ukrainian army over the weekend.
The casualties occurred around three villages in Kursk, where Russia has for four months been trying to quash a Ukrainian incursion, the agency, known by its acronym GUR, said in a public post on the Telegram messaging app.
At least three North Korean servicemen went missing around another Kursk village, GUR said.
On Monday, Pentagon press secretary Maj Gen Pat Ryder said some North Korean troops have died in combat in Kursk, but he did not have a specific number of those killed or wounded. Those troops have primarily been used in an infantry role and started fighting in combat operations about a week ago, Ryder said.
Kremlin spokesperson Dmitry Peskov referred questions to the Russian defence ministry, which did not immediately comment.
North Korea’s leader, Kim Jong-un, has pledged unwavering support for Russia’s invasion of its neighbour under a mutual defence pact.
The alliance gave a jolt to international relations, and the Russian president, Vladimir Putin, said on Monday that the planned deployment of US intermediate-range missiles to Europe and Asia had brought new threats.
“In view of rising geopolitical tensions, we must take additional measures to ensure the security of Russia and our allies,” Putin told a meeting with top military brass. “We are doing it accurately and in a balanced way to avoid being drawn into a full-scale arms race.”
However, military analysts say the language barrier has bedevilled combat coordination between Russian and North Korean troops.
“The poor integration and ongoing communication problems between Russian and North Korean forces will likely continue to cause friction in Russian military operations in Kursk … in the near term,” the Institute for the Study of War, a Washington thinktank, said on Sunday.
On 5 November, Ukrainian officials said their forces had for the first time engaged with North Korean units.
Ukraine seized land in Russia’s Kursk border region last August in the first occupation of Russian territory since the second world war. The operation embarrassed the Kremlin, and aimed to counter unceasingly bad news from the frontline.
The incursion has not significantly changed the war’s dynamics. Over the past year, Russia has been on the front foot, with the exception of Kursk, and has been grinding deeper into eastern Ukraine’s Donetsk region, despite heavy losses.
Russian defence minister Andrei Belousov said the military had been making steady gains in Ukraine, claiming they had accelerated recently, with Russian forces capturing about 30 sq km (11.5 sq miles) of territory a day.
