The announcement followed reports from Ukrainian media outlet Militarnyi, which claimed the soldier was captured by Ukrainian special forces during operations in Russia’s Kursk region.

South Korea's military said on Monday it has detected signs of North Korea preparing to send more troops and weapons, including suicide drones, to Russia to support its war against Ukraine.
