South Korea has said that an international investigation team has provided overwhelming evidence that the country's Cheonan warship was sunk by a torpedo fired from a North Korean submarine
The report states there is no other plausible explanation for the sinking of the Cheonan on 26 March near a disputed sea border between the two Koreas, according to the Washington Post.
The report was based on the findings of an investigation team comprising 50 South Korean experts and 24 investigators from the US, Australia, the UK and Sweden.
North Korea, however, has denied all involvement and intends to send its own investigators to South Korea to examine the evidence.
Investigators said the torpedo parts collected at the explosion site perfectly matched schematics of a North Korean-made torpedo.
South Korean Rear Admiral Hwang Won-dong said that the Cheonan was attacked from international waters by a torpedo fired by a midget submarine and equipped with night-vision technology.
The experts also compared the markings of the exploded torpedo with a previously obtained North Korean torpedo and confirmed that the recovered parts were made in North Korea.
