South, North Korea say they've exchanged warning shots near disputed sea boundary

Both North and South Korea have exchanged warning shots near their disputed western sea boundary on Monday, their militaries said. This comes at a time of heightened tensions over North Korea's recent barrage of weapons tests in response to what the nation calls provocative military drills between South Korea and the United States

North Korea's military said it fired 10 rounds of artillery shells as a warning to South Korea. It accused a South Korean navy ship of intruding into North Korean waters on the pretext of cracking down on an unidentified ship. South Korea's Joint Chiefs of Staff said in a statement that its navy fired warning shots to repel a North Korean merchant ship that it says violated the sea boundary early Monday.
