SEOUL, Nov. 28 (Yonhap) -- South Korea's military ordered civilians on Yeonpyeong Island to evacuate to shelters, military officials here said Sunday, as signs of North Korea's artillery firing were spotted.
"The emergency evacuation order was issued as of 11:18 a.m.," a military official at the South's Joint Chiefs of Staff said. "The military was also put on high alert."
Signs of North Korean provocations were spotted as sounds of artillery fire were heard, the official said.
The South Korean 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. (YONHAP NEWS AGENCY)
The emergency evacuation order came as Seoul and Washington started large-scale naval drills in a show of force against North Korean aggression.
