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. North Korean forces were reportedly redeployed to Russia's Kursk region earlier this month after a temporary withdrawal. Concerns remain that Russia may provide North Korea with advanced weapons technology in exchange for military support. Recent diplomatic talks between Russia and the U.S. signal a shift in U.S. foreign policy regarding the conflict.
