Visitors arrive at the showroom of the Kaesong industrial complex in North Korea, at the Unification Observation Post near the demilitarized zone (DMZ) between the two Koreas in Paju, north of Seoul, South Korea, Thursday, March 28, 2013. A day after shutting down a key military hotline, Pyongyang instead used indirect communications with Seoul to allow South Koreans to cross the heavily armed border and work at a factory complex that is the last major symbol of inter-Korean cooperation.
