South Korea fired warning shots after, Seoul says, North Korean troops crossed their border. The soldiers then went back to the North, Seoul said.

North Korea appears to have sent at least 3,000 more soldiers to Russia early this year, South Korea’s military said Thursday, demonstrating Pyongyang’s continued support for Moscow’s war on Ukraine as world leaders push for an end to the three-year conflict.

South Korea's military said troops aired warning broadcasts and fired warning shots after approximately 10 North Korean soldiers crossed the military demarcation line in the demilitarized zone.
