Summary
British police were questioning five men on Monday on suspicion of explosives and terrorism offences after they were detained near an airbase that has been used by the US to strike Iran. The RAF Fairford arrests took place in the early hours of Sunday, 27 September 2026, close to the village of Whelford in Gloucestershire. Police can hold the men for up to 14 days before they must charge or release them.
The suspects have not been named. Police have not confirmed what the target was, and no link to Iran has been proven. Even so, the RAF Fairford terrorism investigation is already one of the most closely watched security stories in Britain this week.
Background: Why RAF Fairford Matters
RAF Fairford is owned by the UK but run by the US Air Force. It is one of several British bases the American military has used under an agreement dating back to the 1950s. The base sits in the west of England, about 100 miles from London.
The airfield became far more sensitive this year. After the US-Israeli war on Iran began on 28 February, the UK government allowed American forces to use Fairford for strikes. B-52 and B-1 bombers have been stationed there during the conflict.
The government’s permission came with a stated purpose. Britain authorised the US to use bombers from Fairford against Iranian missile sites that were attacking ships in the Strait of Hormuz. That decision made the base a political flashpoint, and Iran was quick to react.
In July, Iran’s Revolutionary Guards warned Britain that any base used to launch attacks on Iran would be treated as a legitimate target. Against that backdrop, any suspicious activity near Fairford was always going to be taken very seriously.
Details: What Happened Near RAF Fairford
Police received a call at about 12:45am on Sunday about three suspicious vehicles heading towards RAF Fairford. Armed officers responded and stopped three vans. Five men were arrested in the Whelford area on suspicion of offences under the Explosives Act, and were then arrested on suspicion of preparing a terrorist act.
A major incident was declared and the area was sealed off. Police evacuated about 85 homes, and residents were asked to gather at Cirencester Leisure Centre. By Monday morning villagers still could not go home, and the vans had not yet been moved.
Army bomb-disposal teams spent hours at the scene. Sky News footage showed a bomb disposal robot moving between three white vans, with the rear doors of two of them open. Police are examining suspected explosives found near the base.
How the operation began is now a point of some confusion. ITV News reported that the operation was not intelligence-led, meaning investigators did not know about a plot in advance. A local farmer says she alerted police after seeing hooded and masked men running into the fields. Donald Trump has given a different account, which is covered below.
Police say this is still an early stage. Investigators have not said what was inside the vans, who the men are, or whether they acted alone. Until charges are brought, the men are suspects and nothing more.
Quotes: What Officials Have Said
Counter-terrorism policing has been careful in its wording. Vicki Evans, the national coordinator for counter-terrorism policing in the UK, said “We are in the early stages of an investigation” and added that police were working with partners to understand what happened.
The prime minister struck a firm tone. Andy Burnham called the situation “deeply concerning” and promised the government would take every step necessary to protect the country.
Donald Trump commented more directly. He said the suspects wanted to do “big damage” and had been under investigation by British and US authorities. He also said the men had been watched for a long time before they were caught. British police have not publicly confirmed that account.
The US military kept its response brief. The US Air Force said its personnel at Fairford “remain vigilant” but would not discuss specific force protection measures. Wes Streeting told the BBC on Monday that he would not speculate on motives while the investigation is live.
Impact: Regional and Global Fallout
The Iran question is the biggest unknown. ITV News understands one line of inquiry is whether representatives of the Iranian regime paid others to carry out a plot on their behalf. No such link has been confirmed, and police have not said that Fairford was the intended target. That distinction matters, and readers should treat early reports with care.
Locally, the effect is immediate. Dozens of families have been kept from their homes, and a 400-metre cordon has disrupted daily life around the base. Fairford is a small community that has already lived with heavy security since the Iran war began.
Diplomatically, the case tests the UK-US relationship. Britain has allowed American bombers to operate from its soil, and any credible threat to those aircraft raises questions about base security. It may also sharpen the domestic debate over whether the UK should host strike missions at all.
Globally, the story lands while tensions around the Strait of Hormuz remain high. If investigators do find a state-backed link, it could widen the dispute between Tehran and Western governments. If they do not, the case may turn out to be a purely criminal matter with no state involvement.
This is not the first time Fairford has drawn attention. In 2003, five anti-war protesters broke into the base and damaged equipment at the start of the Iraq War. That was a peaceful protest with no known link to today’s events, but it shows how long the airfield has been a focal point.
Conclusion: What Happens Next
The next few days will decide how this story is understood. Detectives will keep questioning the men, forensic teams will keep working on the vans, and police must charge or release the suspects within the legal limit. Any charges would reveal what prosecutors believe the men were planning.
For now, the facts are limited. Five men are in custody, explosives-related material is being examined, and the RAF Fairford terrorism investigation is at an early stage. Readers should watch for official police statements, which will be more reliable than speculation.
Frequently Asked Questions (FAQs)
Why did UK police question five men at the airbase?
Police did not arrest the men inside the airbase itself. They stopped three vans in the Whelford area near RAF Fairford after a call in the early hours of Sunday reported suspicious vehicles heading towards the base. Armed officers detained five men on suspicion of offences under the Explosives Act.
The men were then also arrested on suspicion of preparing a terrorist act, which is why counter-terrorism officers took over. Police are now questioning them to learn who they are, what was in the vans, where they were going and who may have sent them. They can be held for up to 14 days before charge or release, and none has been named publicly.
What is the connection between RAF Fairford and US military operations against Iran?
RAF Fairford is a UK-owned airbase operated by the US Air Force, and it is one of several British sites the American military has used since the 1950s. After the US-Israeli war on Iran began in February 2026, the British government allowed US bombers to use it. B-52 and B-1 aircraft have flown from Fairford during the conflict.
The stated purpose was to hit Iranian missile sites that were attacking ships in the Strait of Hormuz. Iran’s Revolutionary Guards warned Britain in July that any base used for such attacks would be a legitimate target. That history is why the base is seen as sensitive, though it does not prove any link to the men now in custody.
What are the latest details of the investigation into the five men?
As of Monday 28 September 2026, five men remain in custody and have not been named. Counter-terrorism police lead the case, and army bomb-disposal experts have been examining three white vans at the scene. Police say they are examining suspected explosives found near the base, and around 85 homes were evacuated as a precaution.
Investigators are considering a possible Iran connection, and ITV News reports one line of inquiry is whether the plot was paid for by representatives of the Iranian regime. Police have not confirmed this, nor have they confirmed that RAF Fairford was the target. Accounts of how the operation began also differ, with some reports pointing to a tip-off from a local farmer and Trump saying the men had been watched for some time. These details may change as the case develops.
