South Korea's military said on Friday that it suspects North Korea is preparing to send more troops to Russia to fight Ukrainian forces, even after suffering losses and seeing some of its soldiers captured.

South Korea’s military says it suspects North Korea is preparing to send additional troops to Russia after its soldiers already deployed on the Russian-Ukraine war fronts suffered heavy casualties

North Korea is likely preparing to send additional troops to Russia after suffering heavy losses in battles against Ukrainian forces, South Korea's military said Friday.

South Korea and NATO on Wednesday urged North Korea and Russia to halt their military cooperation. The demand came after Seoul claimed at least 300 North Korean soldiers died while fighting Ukraine on behalf of Russia.

All North Korean recruits are taught a song that includes a verse about saving their last bullet for themselves to avoid capture, one former soldier told NBC News.

Ukrainian special operations forces have given an insight into the brutal, near-suicidal tactics of the North Koreans they have faced in intense fighting in the Russian border region of Kursk.
