UK police arrest dual British-Iranian national in RAF Fairford terrorism inquiry

Arrest in central London

British counter-terrorism officers arrested a 27-year-old dual British-Iranian national on Thursday in the London borough of Westminster on suspicion of preparing terrorist acts under section 5 of the Terrorism Act 2006. Detectives also questioned a second man, a 26-year-old British national, under caution and executed searches across two residential properties in Westminster. The arrest represents the sixth detention connected to the security operation around the Royal Air Force base at Fairford in Gloucestershire. Investigators confirmed that the 27-year-old remains in custody while specialized counter-terrorism teams examine digital and physical material recovered from the scene.

Security alert in Gloucestershire

The inquiry began in the early hours of Sunday in the village of Whelford, situated directly outside the perimeter of RAF Fairford, roughly 160 kilometres west of London. Gloucestershire police responded after a motorist driving home observed a convoy of white vans carrying masked men in the countryside. Officers arrested five men in their 20s, all from London, on suspicion of explosives offences before broadening the case to terrorism legislation. The five men were released on police bail on Monday after vehicle examinations revealed no explosives, though police confirmed they remain under active investigation.

Assessment of foreign involvement

Detectives and British government officials turned attention toward potential foreign coordination behind the activity near the airbase, which is used by the United States Air Force. Senior national coordinator for Counter Terrorism Policing Vicki Evans confirmed that investigators are exploring potential overseas links.

As we've made clear, we're looking at all possible angles - including possible foreign state involvement.

Prime Minister Andy Burnham stated during the Labour Party conference in Liverpool, following a meeting of the Cobra emergency committee, that intelligence pointed toward Iranian involvement. Burnham noted that British authorities are working closely with US counterparts on the investigation and would not make such assertions lightly. United States Secretary of State Marco Rubio also stated on Tuesday that Washington assessed a foreign actor played a role in the incident.

There are strong indications that Iran played a part in what happened over the weekend at RAF Fairford, but of course it remains an ongoing, complex, and serious police investigation.

Tehran denial and base operations

Iranian Foreign Minister Abbas Araghchi rejected the accusations on Wednesday, arguing that the release of the five initial suspects undermined claims of foreign state backing.

I can confirm Iran's belief that releasing supposed terrorists working for foreign states really says it all. You're barking up the wrong tree.

RAF Fairford has supported long-range American military aircraft during past Middle Eastern operations and throughout the US and Israeli war against Iran that began in February. Burnham indicated in broadcast interviews that the government sees no immediate need to recall Parliament from recess while the police inquiry continues.
