North Korean troops in Russian uniforms moving towards Ukraine, Pentagon says

Some of the 10,000 North Korean troops in Russia are moving closer to Ukraine "outfitted with Russian uniforms and provided with Russian equipment," Defense Secretary Lloyd Austin said Wednesday. 

"I am increasingly concerned that the Kremlin plans to use these North Korean soldiers to support Russia's combat operations in Russia's Kursk region, near the border with Ukraine," Austin said at the Pentagon in a news conference Wednesday with South Korean Defense Minister Kim Yong-hyun. 

Austin said it remains to be seen whether the North Korean troops participate in combat, but "there is a good likelihood" they will, given the high number of casualties on Russia's side.
