Five people were killed and over a dozen injured in a suicide bombing at a mosque used by Shiite Moslems in Pakistan's port city of Karachi Monday evening, police officials said. "Those killed in the bombing included the attacker, one of his two accomplices, a private security guard, a police official and a civilian," police official Tariq Jameel told Deutsche Presse Agentur dpa. Jameel said the bomber walked into the mosque during evening prayers and blew himself up when a police official on security duty intercepted him, dpa reported. An accomplice was killed in an exchange of fire with security officials outside the mosque while a third sustained serious injuries. The injured were being moved to hospitals as local law enforcement agencies were placed on high alert amid mounting tensions in the city's Gulshan-e-Iqbal area, where the mosque is located. Hundreds of angry people in Gulshan-e-Iqbal and its neighbouring areas took to the streets and set ablaze a nearby Kentucky Fried Chicken fast food restaurant, two gas stations and a number of private and public transport vehicles. --More 2206 Local Time 1906 GMT
