Russian experts, who assessed an international probe into the sinking of a South Korean warship in June, are still unable to give any decisive answers, Russian Navy Commander Admiral Vladimir Vysotsky said on Saturday.
The 1,200-ton Cheonan warship sank near the disputed Northern Limit Line in the Yellow Sea on March 26, causing the loss of 46 lives.
In early June, a group of Russian Navy experts went to Seoul to assess an international probe into the incident, which revealed that North Korea fired a torpedo at the vessel from a submarine, although Pyongyang denies the allegations.
"We still have questions about the results of the probe," Vysotsky told the Ekho Moskvy radio station.
Whether the answers will come or not, "doesn't depend on us," he said.
