Mohammed Chatah, a prominent anti-Hezbollah politician and an opponent of Syrian President Bashar al-Assad, is dead Friday after a bomb targeted his convoy in Beirut. The explosion also killed five others and wounded 70.
The Sunni politician was once a senior aide to former Prime Minister Saad Hariri, whose organization is currently engaged in a bitter battle with a militant Hezbollah group.
According to YNet News, the former premier is already accusing Hezbollah of being behind Friday's bombing.
"As far as we are concerned the suspects...are those who are fleeing international justice and refusing to represent themselves before the international tribunal," Hariri said, referring to five Hezbollah suspects indicted for killing his father in 2005.
Friday's blast, the latest in a wave of bombings over the past few months, comes as Lebanon's Sunni and Shiite communities take sides in Syria's civil war. Many are worried Lebanon may be on the brink of plunging into sectarian violence.
