The top United Nations investigator into the murder of former Lebanese Prime Minister Rafik Hariri has presented his latest findings to Secretary-General Kofi Annan.
The report from Detlev Mehlis is to be delivered to the U.N. Security Council Monday, and Mr. Mehlis will brief the council Tuesday.
Mr. Mehlis has said the probe should continue and said he plans to request more interviews with Syrian officials.
An earlier report from U.N. investigators implicated Lebanese and Syrian officials in Mr. Hariri's death.
Meanwhile, Syria's President Bashar al-Assad told Russian television that he would punish any Syrians proven to have been involved in the February killing.
He also warned against possible sanctions by the U.N. Security Council, which has sought to pressure Syria to cooperate with the U.N. probe.
