South Korea's spy agency says an estimated 4,700 North Korean soldiers have been killed or wounded while fighting alongside Russia against Ukrainian forces

The figures show that the number of North Koreans killed and wounded continues to rise. In January, the NIS said about 300 North Korean soldiers had died and another 2,700 had been injured. South Korea's military increased the estimated casualties to 4,000 last month.

Pyongyang this week confirmed for the first time that it had sent troops to help Russia recapture parts of the Kursk region from Ukrainian forces.View on euronews
