South Korean marines patrol on Yeonpyeong island near the western maritime border between the two Koreas, 11 km (7 miles) from the North, about 115 km (71 miles) northwest of Seoul March 12, 2013. North Korea fired dozens of artillery shells at the border island on November 23, 2010, killing two civilians and South Korean soldiers in the heaviest attack on its neighbour since the Korean War ended in 1953. The White House on Monday expressed concern at what it called North Korea's latest provocations aimed at raising tensions and instability in Northeast Asia. (YONHAP/REUTERS)
