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.

In a major battlefield development, Ukrainian troops have destroyed a rare North Korean-made M1989 Koksan self-propelled artillery system in southern Ukraine, military officials announced on July 4 via Telegram.

North Korea is reportedly preparing to send as many as another 30,000 troops to fight for Russia in Ukraine, a massive escalation of its support for Moscow’s war effort, according to Ukrainian intelligence.
