Russian military experts have inspected the wreckage of the South Korean warship Cheonan that sank in the Yellow Sea in March following an alleged attack by Democratic People's Republic of
Korea (DPRK), RIA Novosti news agency reported on Thursday quoting a South Korean military official.
Russian President Dmitry Medvedev sent the experts to South Korea last Monday.
The Russian experts have visited the Pyeongtaek naval base, where the shipwreck has been kept. The results of the inspection have not yet been
announced, but the official said the Russian experts had "asked many questions."
The warship sank near the disputed Northern Limit Line in the Yellow Sea on March 26 with the loss of 46 lives. An international investigation concluded
the explosion was caused by a DPRK's torpedo fired from a submarine.
Pyongyang has strongly denied its involvement.
The Russian investigators have seen fragments of the torpedo, the official said. They have not yet visited the site of the incident, to the south of
the South Korean island of Baengnyeong.
Following the report by international investigators, South Korea froze economic relations and maritime communications with its northern neighbor.
