Ukrainian President Volodymyr Zelensky said Saturday that up to 50,000 North Korean soldiers could be sent to Russia, signaling deepening military cooperation between Moscow and Pyongyang. He did not explain where he got the information, but warned that North Korea could gain valuable battlefield experience and military technology by supporting Russia's war effort. Zelensky also said Kyiv had found some North Korean missiles on Ukrainian territory, though he did not disclose where they were discovered. The claims highlight the expanding role of North Korea in Russia's military operations, as both countries face international isolation. Zelensky's statement adds to previous concerns that North Korea has been supplying weapons to Russia, which Moscow and Pyongyang have denied. There was no immediate response from Russia or North Korea to the latest remarks.
