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

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.

In an unexpected border intrusion, about 10 North Korean soldiers crossed the tense border between North and South Korea, prompting the South to fire warning shots. This marks the first known intrusion by North Korea in nearly a year.
