Report: UK faces worst terror threat since Sep. 11

The threat of homegrown terrorists attacking Britain is greater now than any time since the Sept. 11 attacks in the United States, a British Sunday newspaper reported, citing a leaked intelligence document. More than 2,000 British-based Islamic terrorists are believed to be plotting attacks, according to a government threat assessment prepared this month, which The Sunday Telegraph said it had seen. "The scale of al-Qaida's ambitions towards attacking the UK and the number of UK extremists prepared to participate in attacks are even greater than we previously judged," the newspaper quoted the document as saying.
