Six employees of American fast-food franchise KFC were burned to death in Karachi during a riot that followed a suicide attack on a mosque in the southern Pakistani city, rescue workers said on Tuesday. Angry Shi'ites set fire to the restaurant after the mosque attack in which five people died on Monday night, but the bodies of those burned were only found on Tuesday morning, said Rizwan Edhi of the Edhi Foundation, a private emergency service. "We recovered the bodies of the six people from the debris of the KFC early this morning. All the dead were employees of KFC," he said.Shi'ite mobs often target symbols of U.S. influence after sectarian attacks as they accuse the government of failing to act to prevent religious violence. The attack on the KFC outlet came just minutes after attack on the Karachi mosque. Mobs of angry Shi'ite youths also attacked a hospital, two petrol stations and burned more than a dozen vehicles. Shi'ites make up about 15 percent of Pakistan's mostly Sunni population of more than 150 million.
