North Korea is set to treble the number of its troops fighting for Russia along the front lines with Ukraine, sending an additional 25,000 to 30,000 soldiers to assist Moscow, according to an intelligence assessment from Ukrainian officials.

Kim paid public tribute to North Korean soldiers killed in Russia’s war against Ukraine, part of an effort to cement the two countries’ strategic defense pact.

The addition would almost triple the total number of North Korean soldiers directly fighting alongside Russia in its war against Ukraine.
