The North's military said in a statement Sunday that South Korea planned artillery drills from five front-line islands off the western coast on Monday. It says the drills are "reckless military provocation" and the North will launch "merciless" strikes if the training is implemented. The North warned people living on the islands to evacuate before the drills start. South Korea regularly conducts artillery drills from front-line islands but it's not immediately known whether the South plans to conduct such drills on Monday. A 2010 drill triggered a North Korean artillery bombardment that killed four South Koreans.
