Ukrainian President Volodymyr Zelensky has said there have been more than 3,000 North Korean casualties in Russia's Kursk region.

Despite their elite status, North Korea's "Storm" troops were ill-prepared for the war, South Korea's National Intelligence Service said.

North Korean troops have now entered Russia’s war with Ukraine in a major way, and some have been killed, Western officials say.

Despite the relatively high casualty rate, Zelensky added that North Korea might send even more resources to Russian dictator Vladimir Putin’s armies.

South Korea's military has said that North Korea is preparing to continue aiding Russia in its war with Ukraine, despite casualties.

In Trump-led armistice talks, the Hermit Kingdom may want a seat at the table.

"Through various sources of information and intelligence, we assess that North Korean troops who have recently engaged in combat with Ukrainian forces have suffered around 1,100 casualties," the JCS said in a statement.

North Korean troops are suffering heavy losses in the fighting in Russia's Kursk region and are facing logistical difficulties as a result of Ukrainian attacks, Ukraine’s military intelligence said Thursday.

North Korean troops are suffering heavy losses in the fighting in Russia's Kursk region and facing logistical difficulties as a result of Ukrainian attacks, Ukraine’s military intelligence said Thursday.

Ukrainian forces launched an incursion into the Kursk region in August, dealing a significant blow to Russia's prestige and forcing it to deploy some of its troops from eastern Ukraine, where they were pressing a slow-moving offensive.
