The November 8 bombing took place in a Lebanese Christian neighborhood of Riyadh, and of the seven publicly identified Lebanese victims, six were Christian. Lebanon's newspapers are replete with photographs of Maronite Catholic and Greek Orthodox victims. Daleel al Mojahid, an al Qaeda-linked webpage, praised the killing of "non-Muslims." The Middle East Media Research Institute quotes Abu Salma al Hijazi, reputed to be an al Qaeda commander, as saying that Saudi characterizations of the victims as Muslims were "merely media deceit."
