Five men were arrested near RAF Fairford in Gloucestershire on suspicion of explosives and terrorism offences. Britain’s prime minister said there were strong indications that Iran had played a role. Authorities have not publicly set out the evidence, no conclusion has been announced, and Iran has denied involvement. The case matters because Fairford has been used by U.S. aircraft in operations tied to the Iran war: an unproven allegation now touches a strategically exposed British base.
