Syria is considering a U.N. request to question six Syrian officials in its investigation of the assassination of former Lebanese Prime Minister Rafik Hariri, a Foreign Ministry official said Monday. The official declined to disclose the identities of the people that the U.N. investigators want to question, or say whether the United Nations wanted to question them in Syria or outside, according to a report of the Associated Press.Last week the U.N. Security Council passed a resolution that upgraded the powers of commission, giving Mehlis the right to question anybody at any location and under conditions of his choice. The resolution demanded that Syria cooperate fully with the commission.
