The president of the UN Security Council, Claude Heller, said on Friday that the 15-nation body will meet over the Republic of Korea (ROK)'s warship sinking case.

"I will initiate consultations with members of the Security Council in order to give an appropriate answer to this request," Heller told reporters here after receiving a letter from the ROK UN ambassador.

Heller said that as president of the Security Council, he will circulate the letter to all Council members, "in order that the Security Council could consider duly this matter and respond in an appropriate manner to this request."

Speaking to reporters after meeting with Heller, Park In-kook, the ROK's permanent representative to the UN, said he has " requested the Security Council for its part (act) in a manner appropriate to gravity of situation."

While expressing hope that "the Security Council will start to proceed in accordance with their practice," Park did not specify what action he would expect the Council to take.

He only said he hopes the Security Council will take action that is "commensurate with the gravity of this situation."

Park said that in the meeting he explained what had happened during the sunken naval ship case.

"We have requested the Security Council to respond in an appropriate manner to solve that issue. That is the main gist of that letter," he added.

On March 26, the 1,200-ton ROK Navy frigate "Cheonan," with 104 crew members onboard, went down off the ROK island of Baekryeong off the west coast due to an unexplained explosion that split it into two. Forty-six sailors were killed.

Seoul alleged after investigations that the warship was torpedoed by the Democratic People's Republic of Korea. But Pyongyang denied any involvement in the incident.
