Ukrainian President Volodymyr Zelenskyy said on Monday that more than 3,000 North Korean soldiers have been killed or wounded in Russia's Kursk region and warned that Pyongyang could send more personnel and equipment for Moscow's army.

As the war in Ukraine drags on toward a fourth year, North Korea is preparing to send Moscow more troops beyond the 12,000 already there, as well as additional weapons, including suicide drones, according to the latest assessment from South Korean intelligence.
