North Korea accused South Korea on Monday of committing a serious provocation by firing warning shots during a brief weekend incident in which the South says soldiers from the communist North crossed over their border.
The border shooting came Saturday amid growing tensions over North Korea's threat to test its first atomic bomb. South Korean soldiers rattled off about 40 warning shots after a group of five North Korean troops crossed into the southern side of the no-man's-land separating the divided Korean peninsula, South Korea said.
No one was hurt in the incident.
North Korea's official Korean Central News Agency on Monday called the shooting a "grave military provocation." It said the firing occurred while the North's soldiers were conducting "routine military duty" on their side.
