South Korea's military says North Korea has fired four short-range missiles into the sea off the west coast, in what appears to be the latest sign of Pyongyang's anger over ongoing U.S.-South Korean joint military drills.
The South Korean Joint Chiefs of Staff said in a statement Friday the missiles were launched from North Pyongyan province and traveled about 140 kilometers before landing in the sea. The model of the missiles is not known.
The statement said the North Korean launch appears to be a response to the Foal Eagle military exercise between the U.S. and South Korea, which is set to last another three weeks. Pyongyang has carried out several test launches since the drills began.
The annual war games are a source of regular tension between the two Koreas, who are technically still at war since their 1950s conflict ended in a truce instead of a peace treaty. Pyongyang says it considers the drills to be a preparation to invade, while Washington and Seoul say they are defensive.
