North Korea was conducting live-fire drills from its western coast Sunday, a military source said, the latest in a series of drills near the tensely guarded western border, APA reports citing Yonhap News Agency.
The North Korean military has been conducting the drills north of the South Korean front-line island of Yeonpyeong since around 4 p.m., the source said.
There have been no North Korean artillery shells falling south of the Northern Limit Line (NLL), a de-facto maritime border in the Yellow Sea, and no casualties have been reported, according to the source.
Ongjin County, which has jurisdiction over South Korea's northwestern islands, issued a warning to the border islands as artillery fire was heard from the North Korean side.
