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.

North Korea opened a massive beach resort on its east coast to the public, state-run media reported Wednesday, with Russian guests expected to start arriving next week.

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.
