Some North Korean generals and troops sent to Russia to support Moscow's war in Ukraine might have moved to the battlefield zones, South Korea's spy agency told lawmakers Tuesday. The National Intelligence Service (NIS) shared the information with lawmakers during a closed-door meeting of the parliamentary intelligence committee, according to Rep. Lee Seong-Kweun of the ruling People Power Party and Rep. Park Sun-won of the main opposition Democratic Party. "The mobilization of troops between North Korea and Russia is ongoing," the NIS said. "We are checking the possibility of the deployment of some (North Korean) personnel, including high-ranking military officials, to the front lines." The NIS said the Russian military is teaching over 100 military terms in Russian to North Korean soldiers, noting reports of apparent challenges in communicating due to the language barrier. The agency also assessed that a Russian aircraft traveling between Moscow and Pyongyang on Oct. 23-24 was likely carrying key Russia n security officials involved in the North's troop deployment. On North Korean Foreign Minister Choe Son-hui's recent visit to Russia, the NIS said it likely involved discussions on additional deployments. Source: Yonhap News Agency
