A Saudi militant killed in a recent shootout with security forces plotted last November's attack on an expat housing complex in the capital in which 17 people died, an interior ministry official said Sunday. "Issam Sideek Qassim Mubaraki has been wanted for security matters" since 2003, for being linked to the "deviant group," a term used to refer to al-Qaeda sympathisers in Saudi Arabia. Mubaraki was killed on Saturday when he was spotted by security forces and his car surrounded in the Red Sea port of Jeddah. "He participated in plotting the criminal attack on Al-Muhaya compound (west of Riyadh) housing complex last November," the official SPA agency quoted him as saying. The Nov 8, 2003 car bomb attack on a residential compound in western Riyadh killed 17 people and wounded more than 120, most of them expatriates of other Arab states. The official confirmed earlier reports that another suspect was arrested in the shootout in Jeddah's Al-Jamiaa neighbourhood. Police found a cache of arms in the car, including a revolver, two automatic weapons with 11 magazines, more than 400 bullets and three hand grenades.
