South Korean marines carry their weapons as they walk through a field on the island of Yeonpyeong, which lies on the South Korean side of the Northern Limit Line (NLL), in the Yellow Sea April 8, 2014. In 2010 North Korea fired multiple shells onto the island killing four people, including two civilians in a first such attack since the end of the 1950-53 Korean War. In subsequent years, the South Korean government has increased its military presence on the islands. Cliff tops are adorned with cruise missiles capable of striking Pyongyang, and the beaches are lined with barbed wire, soldiers, and mines. The two sides are still technically at war as the conflict ended in a mere truce, not a treaty. Picture taken April 8, 2014.
