North Korea sends more troops to support Russia in Ukraine

South Korea's spy agency reports that North Korea has sent more troops to Russia to support its military efforts in Ukraine. This follows heavy casualties among North Korean soldiers already deployed in the conflict. The National Intelligence Service is investigating the exact number of additional troops sent. North Korean forces were redeployed to Russia's Kursk region earlier this month after a temporary withdrawal. Reports suggest that between 1,000 and 3,000 North Korean soldiers were deployed to Kursk in January and February. North Korea has been supplying weapons to Russia and may receive economic assistance in return.
