Reasons for this attack are unknown. 58 sailors are rescued, but 46 were lost and presumed dead. Though not much evidence was initially available, the common theory among the U.S. and South Korean governments was that North Korea had been behind the attack. North Korea had reportedly been running numerous artillery drills on the same day the ship was sunk. On May 20, 2010, following the results of an investigation conducted by experts from the US, Australia, Britain and Sweden, the South Korean government formally blamed the North Korean government for the sinking of the Cheonan.
