Gen Wissam al-Hassan. Video from the scene showed protesters clashing with security forces and tear gas being fired. The protests came after a series of political speeches were given to the crowd gathered in Beirut's central square for the funeral. A crowd surged from the central square toward the prime minister's office, growing in number and in intensity. Dozens rushed toward police lines. Some politicians had called for a day of rage Sunday, two days after the most high-profile assassination in Lebanon in more than seven years. Al-Hassan and two others died in Friday's car bombing. Some Lebanese political leaders have called for a day of protests as accusations over who's responsible homed in on the Syrian regime of Bashar al-Assad. The attack -- in broad daylight, at one of the capital's busiest intersections -- left a crater more than a meter deep. Syria condemned the blasts very quickly after they happened on Friday.
