Visitors take their souvenir pictures near a military barbed-wire fence at the Imjingak Pavilion near the border village of Panmunjom, which has separated the two Koreas since the Korean War, in Paju, north of Seoul, South Korea, Wednesday, March 6, 2013. North Korea's military is vowing to cancel the 1953 cease-fire that ended the Korean War, straining already frayed ties between Washington and Pyongyang as the United Nations moves to impose punishing sanctions over the North's recent nuclear test.
