"We see a lot of contradictory information," spokesperson Dmitry Peskov told the Russian media, the state-controlled news agency Interfax reported."The South Koreans say one thing, and then the Pentagon says that they have no confirmation, so there is a lot of contradictory information. So that's probably how it should be approached."The U.S. is yet to confirm the presence of the North Korean troops in Russia or Ukraine, though a senior U.S. lawmaker said such a step would mean crossing a "red line" and necessitate immediate action."(North Korea) is our close neighbor and partner, and we are developing relations in many spheres, which is our sovereign right," Peskov said, claiming that this cooperation is "not directed against third countries."The spokesperson said questions regarding the conduct of the war should be directed toward the Defense Ministry.
