South Korean vehicles turn back their way as they were refused for entry to North Korea's city of Kaesong, at the customs, immigration and quarantine office in Paju, South Korea, near the border village of Panmunjom, Wednesday, April 3, 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.
