The Cheonan sinking

On March 26th 2010 a South Korean naval ship, the Cheonan, sank after an explosion on board. 48 sailors were killed in an alleged torpedo attack carried out by North Korea. The North Korean authorities have always denied any involvement. Bugyeong Jung has been speaking to a survivor of the attack about what happened that night.
