North Korean ballistic missiles fired at Ukraine by Russian forces since late December have been far more precise than salvos of the weapons launched over the past year, two senior Ukrainian sources told Reuters.

A Ukrainian news outlet has published a video showing the capture of a North Korean soldier, as South Korea's spy agency said Kim Jong Un has pulled troops from Russia's Kursk region. Newsweek has contacted the Russia's Foreign Ministry for comment.

The commander described the North Korean troops as "cannon fodder" and said their behavior in combat was erratic.

Experts say Pyongyang’s advancing missile technology raises global security risks and threatens regional stability.
