S. Korean Arrested for Unapproved Trip to North South Korean police have arrested a pro-North Korean activist for making an extended trip to Pyongyang without government approval. Police in Seoul said they took No Su-hui into custody Thursday after he crossed the Demilitarized Zone into South Korea. No went to Pyongyang in March, defying South Korean law banning citizens from traveling to North Korea without permission. The Korean Peninsula has remained in a state of war since a truce was signed in 1953 to end three years of fighting. With relations at a low point, the government has allowed only a handful of South Koreans to visit Pyongyang in recent years. Last year, a Christian minister was sentenced to prison for making a similar unauthorized trip. North Korean state media confirmed that No had returned to South Korea.
