South Korean employees working at the Kaesong Industrial Complex (KIC) change their license plates authorized by North Korea, to South Korean ones, upon arrival at the South's Customs, Immigration and Quarantine (CIQ) area, just south of the demilitarised zone separating the two Koreas, in Paju, north of Seoul, April 4, 2013. North Korea barred entry to a joint industrial complex it shares with the South for a second day on Thursday, the South Korean Unification Ministry said, but would allow 222 South Korean workers to leave the zone through the day.
