The US withdrew its bombers from RAF Fairford after an investigation into an alleged planned terrorist attack on the base. At least 10 B-1 bombers used by the US military in the Iran conflict flew out of Fairford on Sunday, suggesting US officials were taking the threat seriously. Last week, five men in three vans near the military base were arrested, followed by a sixth British-Iranian national. All were released on bail, drawing criticism from the Pentagon.
