A new round of naval firing drills in South Korea is scheduled to steer clear of border islands, defense officials told the Yonhap News Agency on Sunday. The exercises, which will start Monday and end Friday, will take place off coasts on all sides of the country, the South Korean agency reported. None are scheduled near the Yellow Sea islands south of the maritime border with North Korea, defense officials said, but more locations could be added to the list. They come after similar live-fire drills conducted by South Korea last week. Tensions mounted between the Koreas on November 23, when North Korea shelled South Korea's Yeonpyeong Island. The attacked killed two marines and two civilians and injured 18 people.
