A bomb attack in Beirut has killed an anti-Syrian member of Lebanon's parliament, his son, and at least eight other people.
Allies of the slain politician, Walid Eido, blame Syria for the attack.
Lebanese officials say about 10 other people were wounded when a bomb-rigged car exploded and destroyed Eido's vehicle near the Beirut seafront.
Late Wednesday, Lebanese Prime Minister Fuad Siniora called for a meeting of Arab foreign ministers to discuss the lawmaker's murder.
In Washington, a U.S. State Department spokesman, Sean McCormack called the bombing an act of terrorism. France also condemned the blast.
Seven anti-Syrian figures in Lebanon, including former prime minister Rafik Hariri, have been killed in similar bombings or other attacks since 2005.
The United Nations this week started to put together an international tribunal to try suspects in the Hariri killing -- a step strongly opposed by Syria and its Hezbollah-led allies in Lebanon. Syria has denied involvement in the killings.
A string of bombings also has occurred since fighting broke out last month between Lebanon's army and Islamic militants at a Palestinian refugee camp near the northern city of Tripoli.
Two soldiers were killed Wednesday as troops continue to battle the Fatah al-Islam militants at the Nahr al-Bared refugee camp.
Tens of thousands of refugees have left the area, but many remain at the camp.
More than 130 people have been killed since fighting began more than three weeks ago.
