South Korean vehicles return from a joint industrial complex of North Korean city of Kaesong at the customs, immigration and quarantine office, near the Demilitarized Zone (DMZ) of Panmunjom in Paju, north of Seoul, South Korea, Thursday, March 28, 2013. Raising tensions with South Korea yet again, North Korea said it cut the last military hotline with Seoul because there was no need for communications between the countries in a situation "where a war may break out at any moment."
