Russia and Ukraine dispute the status of the Kursk region, which Kyiv invaded last year in a surprise and successful incursion into Russian territory.

Russian officials confirmed for the first time publicly that North Korean soldiers have been fighting alongside them in the war in Ukraine, as U.S. President Donald Trump shows his patience is running thin with Russia on peace talks in Ukraine.

The General Staff of the Armed Forces of Ukraine has reported that since the start of the Kursk operation, Russia has lost more than 62,000 soldiers and more than 4,500 North Korean servicemen in the Kursk operational zone.
