A jailed extremist Muslim cleric named by Britain's government as a key influence on one of four men who carried out the 2005 London transport bombings was deported to Jamaica Friday, the home secretary said. Abdullah el-Faisal, a Jamaican-born convert to Islam, was placed on a flight to Kingston, Jamaica Friday afternoon, Home Secretary John Reid said. He said el-Faisal was barred from re-entering Britain. "We are committed to protecting the public and have made it clear that foreign nationals who abuse our hospitality and break our laws can expect to be deported after they have served a prison sentence," Reid said. "We will not tolerate those who seek to spread hate and fear in our communities," he said.
