Two Koreas exchange gunfire

SEOUL (Reuters) - North and South Korean troops exchanged gunfire across their heavily fortified border for the first time in about a year, a military official said on Tuesday.

North Korean troops fired two shots at a South Korean guard post near the Demilitarized Zone late on Monday and South Korean troops returned six shots, an official said by telephone.

"No one was injured in the incident," the Joint Chiefs of Staff official said, referring to South Korean troops. There was no word if any North Korean soldiers were hurt.
