A dozen B-1 bombers stationed at Gloucestershire base were redeployed to US on Sunday amid concerns over possible threat from Iran

Downing Street has insisted RAF Fairford is secure a day after the US air force suddenly withdrew a dozen B-1 bombers that had been stationed at the Gloucestershire base amid security concerns about a possible threat from Iran.

The prime minister’s official spokesperson, speaking during a scheduled briefing, said “yes” when asked if the military site was safe – contrasting with the concern showed by the US military during the hasty redeployment the day before.

The US Air Force has pulled its bombers from RAF Fairford following an investigation into an alleged planned terror attack at the base.

The bombers were redeployed back to their home bases in the US, according to a Pentagon official who was not authorised to discuss sensitive military movements and spoke on Sunday on condition of anonymity.
