Officials in South Korea now claim to have proof for what they havesuspected for months: A North Korean torpedo is to blame for sinking one of their navy’s ships in late March, which left 46 South Korean sailors dead. With help from the United States, South Korea’s investigation has concluded that "evidence overwhelmingly proves" a North Korean torpedo caused a “strong underwater explosion,” splitting apart the large ship. South Korea promised it would take action against the attack, but North Korea continues to deny any involvement in the incident. U.S. Secretary of State Hillary Clinton is due to arrive in Seoul next week to mediate the fallout. Officials in the U.S., Britain, and Japan quickly condemned the totalitarian state for the report's findings. Capturing world sentiment, Japan's prime minister called the attack "unforgivable."
