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

Russian President Vladimir Putin declared a three-day ceasefire in the war with Ukraine next month to celebrate the Soviet Union’s victory over Nazi Germany during World War II.

President Trump "wants to see a permanent ceasefire first, to stop the killing, stop the bloodshed," press secretary Karoline Leavitt said.
