The South Korean checkpoint of Paju on the border with North Korea is deserted on May 3, 2013

South Korea’s border checkpoint in Paju is deserted on May 3, 2013 after the South withdrew its last remaining workers from the joint industrial zone in Kaesong, North Korea. South Korean police have stopped a planned launch of anti-North Korean leaflets across the tense border, sparking an angry protest from activists, witnesses said.
