More than 3,000 North Korean soldiers have been killed or wounded in Vladimir Putin’s Ukraine war, claims Volodymyr Zelensky.

The Russians engaged soldiers from North Korea in the Kursk region, where they first encountered drones. The method of combating drones by North Korean soldiers was found by Ukrainian special forces in a captured notebook.

North Korea has lost more than 3,000 troops in about two months of combat in Russia’s Kursk region, Ukrainian President Volodymyr Zelensky said Monday — and he criticized world leaders for doing “almost nothing” to counter Moscow’s alliance with Pyongyang.
