Downing Street has insisted RAF Fairford is safe after the United States withdrew all its bombers from the Gloucestershire airbase.
The Pentagon confirmed on Sunday that the aircraft, believed to include about a dozen B-1 bombers, had been moved back to their home stations in the US.
US media reported that a new threat was behind the decision. The withdrawal followed an incident on 27 September, when police were alerted to three suspicious vehicles near RAF Fairford.
The base is operated by the US Air Force. Whitehall sources have not disputed reports that the removal of the bombers was linked to the incident.
A Downing Street spokesperson said they would not comment on foreign military operations, but insisted the base was safe. The spokesperson also referred to comments by US President Donald Trump praising British police, defence and security services.
US Secretary of State Marco Rubio said the US retained full confidence in the security of its bases and that British authorities had been cooperative since the incident.
The earlier incident is being investigated by counter-terrorism police. Five men aged between 23 and 25 were initially arrested after vehicles were reported travelling towards the base.
The US has now returned all bombers deployed at RAF Fairford to bases in America.
