The US Air Force abruptly withdrew about a dozen B-1 bombers from RAF Fairford in Gloucestershire, UK, over security concerns tied to a possible Iran-linked threat, days after five men were arrested near the base in connection with an alleged planned terrorist attack, followed by a sixth, British-Iranian suspect; all were later released on bail. Downing Street insisted the base remains secure, while the sudden redeployment drew scrutiny in the UK over the scale of the security threat. The incident reflects growing concern in Britain about being drawn into the fallout of the US-Iran conflict despite the UK's official non-involvement.
