GLOUCESTERSHIRE, UK – Counterterrorism police in Britain are investigating an incident near RAF Fairford in Gloucestershire after officers arrested five men on suspicion of preparing a terrorist act. The arrests followed reports from local residents of three suspicious vehicles moving toward the air base overnight.
Police later said the men are all British nationals between 23 and 25 years old. Authorities have not said exactly what was found in the vehicles, and they have not disclosed whether the men have been charged. The investigation remains active, with a cordon still in place around part of the area.
How police say the incident unfolded near the airfield
Gloucestershire police said the first call came at 00:45 local time on Sunday, after someone reported three vehicles behaving suspiciously near the base. Armed officers responded, and the force later said the matter had been contained.
A 400-meter cordon was put up around the site, and broadcast footage showed a bomb disposal robot near vans with their rear doors open. Police also advised about 85 households in nearby Whelford to leave their homes temporarily. Residents said the village had seen more police patrols in recent weeks and that tensions had already been rising in the area.
The counterterrorism investigation has since taken over from local police. Officials say significant resources, including military assets, are still deployed as investigators continue their work on scene.
Who was arrested and where they are from
Police identified the five arrested men as residents of London. They are a 24-year-old from Camden, a 24-year-old from Westminster, a 25-year-old from Westminster, a 23-year-old from Westminster and a 24-year-old from Willesden.
The men were arrested in Whelford on Sunday morning on suspicion of offences under the Explosives Act and preparing a terrorist act. They remain in custody, and police have not said where they are being held.
Britain’s counterterrorism police have cautioned that the case is still at an early stage. Officials have not publicly described any motive, nor have they said whether any additional suspects are being sought.
Why RAF Fairford drew attention from security officials
RAF Fairford is a British military base in Gloucestershire that hosts the United States Air Force’s 501st Combat Support Wing. It is one of several UK bases connected to US military operations, including RAF Lakenheath and RAF Mildenhall.
The Fairford site has been used by US forces during strikes on Iran in the current conflict, including deployments of B-1 and B-2 bombers from the base. In March, then-Prime Minister Keir Starmer gave permission for defensive US action against Iranian missile sites from Fairford and Diego Garcia in the British Indian Ocean Territory.
That context has made the investigation especially sensitive, but British officials have not confirmed any link to Iran. They have described the matter as serious and complex while asking the public to avoid speculation.
What officials and residents said after the arrests
United Kingdom Prime Minister Andy Burnham described the incident as deeply concerning and said the government would take every necessary step to protect the public. Foreign Secretary Ed Miliband said it was a reminder of the threats the country faces and praised security services, soldiers and police for their work.
On Monday, the Foreign Secretary also said the UK must be ready to confront security threats facing Europe and the wider world. He added that Britain would act against what he called Iran’s proxies, though authorities have not publicly tied the arrested men to any foreign state.
A local resident who called emergency services told the BBC she found her driveway blocked when she returned home and saw a large group of hooded and masked men. She said armed officers arrived within minutes after she dialed 999 and that she was shocked the alert came from a member of the public rather than from the base itself.
How Iran and U.S. officials responded
Iran’s embassy in London denied any connection between Tehran and the men arrested near RAF Fairford. In a statement on X, it rejected what it called unfounded and malicious speculation linking Iran to the case and accused some British voices and media outlets of spreading anti-Iran sentiment.
U.S. President Donald Trump said the suspects were looking to do major damage at the air base and said the United States and Britain had been working together on the case. British officials have been far more cautious, saying it would be irresponsible to speculate about Iran’s role.
Defence Secretary Wes Streeting said he had spoken with U.S. Defense Secretary Pete Hegseth and that Britain was working closely with American partners. Counterterrorism coordinator Vicki Evans said the operation involves local and national police, the Ministry of Defence and other agencies, and that investigators need space to continue their work carefully.
Questions still open as the cordon remains in place
Several details about the case have not been made public. British law generally keeps the identities of suspects private unless charges are filed, and investigators have not said what was inside the vehicles or whether the men were being watched before the arrest.
Security analyst Rob Geist Pinfold said Trump’s comments raised questions about whether the men had already been under scrutiny and how close they were able to get to the base before the public alert. He said it is still unclear whether this was a clumsy approach caught by chance or a more deliberate plan that failed.
For now, police are continuing to hold the scene and limit disruption to nearby communities. Officials say the operation is still active, and they are asking residents in the area for patience while the investigation continues.
