Korean Navy Boats Exchange Warning Shots

North and South Korean naval patrol boats have briefly exchanged fire near their disputed maritime border, according to the South's defence ministry, which said the North's vessel had violated the boundary. The incident took place around 9:50am (00:50 GMT) on Tuesday near the South Korean border island of Yeonpyeong, when the North Korean patrol boat crossed into the South's water, a ministry spokesman told AFP news agency.
