Lebanon has asked foreign experts to help in the investigation of the killing of former Prime Minister Rafik Hariri.
Judiciary officials say Swiss DNA and explosives experts will be helping with the probe into Monday's car bombing in Beirut that killed Mr. Hariri and at least 14 others.
Mr. Hariri was laid to rest at a Beirut mosque Wednesday after an emotional and politically charged funeral. Hundreds of thousands of mourners jammed the city for the funeral.
Many mourners chanted anti-Syrian slogans. Lebanese opposition politicians blamed the killing on Syria, the main power broker in Lebanon. Damascus insists it had no role in the murder.
U.S. Assistant Secretary of State William Burns has called for the withdrawal of Syria's 14,000 troops from Lebanon. Washington recalled its ambassador to Syria earlier this week.
