The United States has confirmed that North Korean troops have been transported to Russia, with at least 3,000 soldiers arriving in Vladivostok. The US assessed that these troops were trained at multiple military sites in eastern Russia before being deployed. White House Spokesperson John Kirby emphasized that if these North Korean soldiers engage in combat in Ukraine, they will become "legitimate military targets." Both Russia and North Korea have denied the claims, with Russia labeling them as "fake news" and a North Korean representative calling it "groundless rumors."
