North Korea is testing its new weapons on Russia’s side in the war, and Ukrainian officials say the North’s troops are also gaining direct battle experience.

U.S. Deputy Secretary of State Kurt Campbell said Wednesday that Washington and its allies are “alarmed” by North Korea’s nuclear and missile threats as well as its increasing military support for Russia's war in Ukraine,

Ukrainian media reports indicate that Russia is organizing a battalion of North Korean nationals to assist in driving Kyiv's forces out of Kursk.
