SEOUL, Nov. 28 (Yonhap) -- South Korea's military had ordered civilians on a border island to evacuate to shelters, military officials said Sunday, after hearing sounds of "several rounds" of artillery firing, though no shells landed on the island.
While the emergency evacuation order on Yeonpyeong Island, devastated by North Korea's artillery attack on Tuesday, was lifted, military officials said they are keeping a close watch on the movements of the North's coastline artillery batteries as they maintain a "ready-to-fire" posture.
"The evacuation order was issued after sounds of several rounds of North Korea's artillery were heard on Yeonpyeong," said an official at the South's Joint Chiefs of Staff (JCS).
The JCS official said, however, the distant sounds of artillery firing came from the North's firing training inside its territory, not the coastline artillery near the island.
The evacuation order came hours after Seoul and Washington started large-scale naval drills in the Yellow Sea in a show of force against North Korean aggression.
The island was shelled by North Korea on Tuesday. Two marines and two civilians were killed in the North's artillery attack. Most of some 1,700 civilian residents on the island have already left the island, but some 20 residents are still there.
