North Korea sends more troops to support Russia's Ukraine war

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 reportedly redeployed to Russia's Kursk region earlier this month. North Korea has previously supplied weapons to Russia and sent thousands of troops last fall. Concerns remain about potential military technology transfers from Russia to North Korea in exchange for support.
