Torpedo fired at South Korea from North Korea?

In March a South Korean Ship was hit by a torpedo. The blast killed the 46 sailors that were onboard the ship. South Korea blamed North Korea for the ordeal. But then North Korea denied it and said that South Korea is now tampering with the evidence of the ship. The 1,200 ton corvette sank after a mysterious explosion tore it into half near disputed waters off North Korea on March 26. "The evidence points overwhelmingly to the conclusion that the torpedo was fired by a North Korean submarine," said Dr Yoon Duk-yong, co-chair of a military group formed to investigate the incident. Some submarines set off from North Korea naval base three days before the attack. People believe that one of the "salmon" colored submarine (equipped with nightvision) was the one who attacked the South Korean Ship. The White House backed the report, saying it "points overwhelmingly to the conclusion that North Korea was responsible for the attack."
