Downing Street has insisted RAF Fairford is safe, after the US withdrew all of its bombers from the military base.

The Pentagon confirmed on Sunday it had removed its bombers - thought to be about a dozen B-1s - from the base back to their home stations in America.

US media reported a new threat led to the bombers being removed, which follows a major incident on 27 September when police were alerted to three “suspicious vehicles” near the airbase.
