South Korea's government is expected to soon release a 250-page investigation into the sinking of one of its warships.

An international panel concluded that a North Korean torpedo sank the Cheonan in March - a charge Pyongyang has denied.

Now some naval experts have also contested the finding and suggest a government cover-up of a simple accident.
