The U.N. Security Council has unanimously adopted a resolution demanding that Syria comply with the U.N. probe into the assassination of former Lebanese Prime Minister Rafik Hariri.

The Western-sponsored resolution warns of unspecified "further action" if Syria does not comply with investigators. In last-minute negotiations, Security Council members agreed to drop references to economic sanctions after some members objected. 

The United States, France and Britain pressed for the resolution after last week's U.N. report implicated top Syrian and Lebanese security officials in the February bombing that killed Mr. Hariri and 20 others. Monday's resolution demands Syria impose a financial freeze and travel ban on suspects named in the probe.

Secretary of State Condoleezza Rice said Monday the resolution makes it clear Syria faces serious consequences if it does not comply with the probe into the killings. 

Syria has criticized the U.N. report and vowed to open its own probe.
