The family of slain former Lebanese Prime Minister Rafik Hariri has welcomed the findings of a U.N. report which has linked top Syrian and Lebanese security officials with his killing. Saad Hariri, Rafik Hariri's son and a leader of Syria's opponents in the Lebanese parliament, said in a televised address on Saturday from Jeddah, Saudi Arabia, that his family wants justice, not revenge. He also called for the perpetrators to be brought before an international tribunal. At a news conference in Damascus, a foreign ministry official said Syria had cooperated with the U.N. investigation led by German prosecutor Detlev Mehlis. He repeated Syrian denials of involvement in the killing and said the report was biased and lacked evidence. In Beirut, the Cabinet is to discuss the findings, which concluded the decision to kill Mr. Hariri on February 14 "could not have been taken without the approval of top-ranked Syrian security officials" in collusion with their Lebanese counterparts.
