Home-grown British terrorists now regard themselves as part of “global insurgency” that poses a new threat to international security, according to an official US report published yesterday.

The finding, in the State Department’s annual country report on terrorism, reflects growing fears on both sides of the Atlantic about radicalised young British Muslims.

British intelligence chiefs have confirmed to The Times that they are worried by the prospect of the next attack in America being committed by a British citizen arriving without hindrance in the US on the visa waiver programme. They are liaising closely with the FBI to identify possible suspects.
