Ukraine's military intelligence says that North Korean troops are suffering heavy losses in the Kursk region and are facing logistical difficulties as a result of Ukrainian attacks.

North Korean soldiers fighting for Russia were given fake military documents with Russian names and birthplaces, the Ukrainian military said, amid claims from Kyiv that Russia is trying to conceal the presence of foreign fighters on the battlefield.

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