North Korea is likely preparing to send additional troops to Russia after suffering heavy losses in battles against Ukrainian forces, South Korea's military said Friday.

Kim Jong Un's soldiers have joined the Russians in the war against Ukraine. Although North Korean military personnel are suffering heavy casualties in the battles, they have also developed a method for destroying Ukrainian drones.

South Korea’s Joint Chiefs of Staff also assessed in a report Friday that North Korea is continuing its preparations to test-fire an intercontinental ballistic missile.
