The gateways to the North Korea's city of Kaesong are shut down at the Inter-Korean Transit Office in Paju, South Korea, near the border village of Panmunjom, Thursday, April 4, 2013. North Korea on Wednesday barred South Korean workers from entering a jointly run factory park just over the heavily armed border in the North, officials in Seoul said, a day after Pyongyang announced it would restart its long-shuttered plutonium reactor and increase production of nuclear weapons material.
