UK police hold five near U.S. bomber base on suspicion of preparing a terrorist act

British counter-terrorism police said five men arrested overnight near RAF Fairford — a U.K. base operated by the U.S. Air Force and used for limited strikes on Iranian missile sites — are being held on suspicion of preparing a terrorist act. About 85 homes were evacuated while army specialists examined three vans. President Trump said the suspects had been looking to do "big damage."

Editor’s note: Arrest facts, cordon, evacuations, and charge language follow Associated Press (via PBS NewsHour, updated Sep 27, 2026), AFP/France 24, and Reuters wraps the same day. Trump quotes are as reported by AP and Reuters. Motives — including any Iranian, Russian, or Islamist link — remain unconfirmed; U.K. Defence Secretary Wes Streeting said it would be "irresponsible to speculate," and Counter Terrorism Policing describes the inquiry as early-stage. A Reuters-cited anonymous source floated Iran as the most likely line of inquiry among several; that is not an official finding. Fairford's role in limited U.S. strikes on Iranian missile sites under a prior U.K. government agreement is attributed to AP/AFP reporting.

British counter-terrorism police said Sunday that five men arrested overnight near RAF Fairford — a U.K.-owned air base operated by the U.S. Air Force and used for limited American bomber strikes on Iranian missile sites — are being held on suspicion of preparing a terrorist act. Local officers first detained them on suspicion of Explosives Act offences after a 12:45 a.m. call about three suspicious vehicles heading toward the base in Gloucestershire.

What happened: Armed officers arrested the five men in the Whelford area adjoining Fairford. Counter Terrorism Policing, led through London's Metropolitan Police, took over the inquiry. Police said a 400-meter (about 1,300-foot) cordon stayed around the three vans while army explosive-ordnance specialists examined them; aerial TV footage showed a bomb-disposal robot working near open rear doors. About 85 households were evacuated as a precaution, with some taken to a nearby recreation center. Gloucestershire Police called the situation "contained."

Why Fairford matters: The base hosts the headquarters of the U.S. Air Force's 501st Combat Support Wing and the 420th Air Base Squadron. Under an agreement reached when Keir Starmer was prime minister, Washington has used Fairford for strictly limited "defensive" strikes against Iranian missile sites in the war that began Feb. 28. Iran has previously called bases used to attack its territory legitimate targets. A U.S. Air Force statement said no U.S. personnel were involved in Sunday's incident and that forces "remain vigilant" without discussing specific force-protection steps.

U.S. and U.K. response: President Donald Trump, speaking to reporters in Chicago, praised the operation and said the suspects "were looking to do big damage" and had been "under view for a long time," with U.S. and British authorities working together. Prime Minister Andy Burnham thanked police, the armed forces, and evacuated residents and urged people "not to speculate while the authorities establish the full facts." U.K. Defence Secretary Wes Streeting said he had spoken with U.S. Defense Secretary Pete Hegseth; asked about Iranian involvement, Streeting said it would be "irresponsible to speculate."

What is not confirmed: Police have not named the men, given nationalities, or stated a motive. Suspects held under the Terrorism Act can be detained without charge for longer than ordinary arrests — up to 14 days under that law, AP noted. Some U.K. reporting said the overnight response was not intelligence-led. Reuters cited a source familiar with the inquiry who called an Iranian-linked motive the most likely among lines of inquiry that also include Russian sabotage or an Islamist plot; that remains an anonymous assessment, not an official finding.

Why it matters: An alleged plot at a forward U.S. bomber base in Britain would escalate the security risk around the Iran war onto allied soil and test U.S.–U.K. base security just as Hormuz diplomacy remains stalled. Even with motives unresolved, the evacuations, bomb-disposal work, and leaders' public comments underline how tightly the Middle East conflict now touches European host-nation communities.

What's next: Watch for charging decisions or further Terrorism Act arrests, any official word on motive or foreign-state links, whether the Whelford cordon is lifted, and any changes to force-protection levels at other U.S.-used U.K. bases (Reuters reported heightened security at RAF Lakenheath and Mildenhall on Sunday).
