One of Lebanon's key anti-Syrian politicians is urging Syria to cooperate with the United Nations probe of the assassination of former Lebanese Prime Minister Rafik Hariri.
Druze leader Walid Jumblatt also backed calls by Mr. Hariri's son, Saad, for an international tribunal to try those responsible for the February bomb attack.
The U.N. report, issued last week, implicated Lebanese and Syrian officials in the killing. It said Syria's cooperation in the probe was limited.
Syrian officials dismissed the credibility of the U.N. report.
Meanwhile, Lebanese police arrested a man who the U.N. report says telephoned Lebanon's pro-Syrian President Emile Lahoud minutes before Mr. Hariri was killed. A spokesman for Mr. Lahoud has strongly denied the president had been in contact with Mahmoud Abdel-Al.
