North and South Korea fired hundreds of artillery shells into each other's waters Monday in a flare-up of animosity that forced residents of five front-line South Korean islands to evacuate to shelters for several hours, South Korean officials said.
The exchange of fire into the Yellow Sea followed Pyongyang's sudden announcement that it would conduct live-fire drills in seven areas north of the Koreas' disputed maritime boundary. North Korea routinely test-fires artillery and missiles into the ocean but rarely discloses those plans in advance. The announcement was seen as an expression of Pyongyang's frustration at making little progress in its recent push to win outside aid.
North Korea fired 500 rounds of artillery shells over more than three hours, about 100 of which fell south of the sea boundary, South Korean Defence Ministry spokesman Kim Min-seok said. South Korea responded by firing 300 shells into North Korean waters, he said.
No shells from either side were fired at any land or military installations, but Kim called the North's artillery firing a provocation aimed at testing Seoul's security posture. There was no immediate comment from North Korea.
In Washington, White House spokesman Jonathan Lalley called North Korea's actions "dangerous and provocative" and said they would further aggravate tensions in the region.
Monday's exchange was relatively mild in the history of animosity and violence between the Koreas, but there is worry in Seoul that an increasingly dissatisfied North Korea could repeat the near-daily barrage of war rhetoric it carried out last spring, when tensions soared as Pyongyang threatened nuclear strikes on Washington and Seoul in response to condemnation of its third nuclear test.
