(STR/AFP/Getty Images) Summary Moderate Lebanese Sunni politician Mohamad Chatah, a highly outspoken critic of Syria and Hezbollah, was killed in a car bombing Dec. 27 in Beirut's upscale central business district. The bombing was similar to the attack that killed former Lebanese Prime Minister Rafik al-Hariri in 2005; in fact, it occurred just a few blocks from where Chatah's own motorcade was struck. The prevailing assumption is that Hezbollah conducted the attack as a show of force against Lebanon's Saudi-backed Future Movement, which is led by the al-Hariri family. Indeed, the sophistication of the attack does suggest the involvement of a professional organization such as Hezbollah. Either way, the Dec. 27 attack may create more problems at home for Hezbollah as the group tries to hold its ground in Syria. Analysis
