South Korea 's foreign minister said Wednesday it was "obvious" that North Korea sank one of the South's warships in March, killing 46 sailors.
Foreign Minister Yu Myung-hwan told reporters that investigators have enough evidence of North Korean involvement in the sinking of the Cheonan to warrant taking Pyongyang to the U.N. Security Council, Washington Post reports.
Mr Yu's remarks came as a multinational team prepares to announce the results of its investigation into the incident. It is the clearest indication to date from South Korea that it blames Pyongyang for the incident.
North Korea has denied responsibility for the incident, which has increased tensions between the two nations, BBC News says.
