British counterterrorism police are investigating a possible Iran connection after five men were arrested near a U.S.-used air base on suspicion of preparing a terrorist act.
Police received a call shortly after midnight Sunday about three suspicious vehicles apparently traveling toward RAF Fairford in Gloucestershire, England, near the southern Welsh border. Armed officers stopped the vehicles and arrested five men in nearby Whelford on suspicion of explosives offenses.
The men were later also arrested on suspicion of preparing a terrorist act, according to Counter Terrorism Policing.
Investigators are examining whether the suspected plot is linked to Iran, according to multiple reports. A source familiar with the investigation told Reuters that an Iran-linked motive is considered the leading possibility, while Russian sabotage and an Islamist plot are also being examined.
British authorities have not publicly identified a motive or said who they believe was behind the alleged plot.
RAF Fairford has played a role in U.S. military operations during the war with Iran. American B-1 and B-52 bombers have operated from the base, including for strikes on Iranian missile sites.
Iran‘s Revolutionary Guards warned Britain in July against allowing U.S. bombers to operate from Fairford, saying bases used for attacks on Iranian territory could become legitimate targets.
Police established a roughly 400-meter cordon around the vehicles while an explosive ordnance disposal team examined them. About 85 nearby households were advised to evacuate as a precaution.
President Donald Trump said Sunday that U.S. and British authorities had worked together on the investigation and claimed the suspects intended to cause “big damage.”
“We had them under investigation,” Trump told reporters. “They were looking to do big damage to our fort.”
British authorities have not publicly confirmed Trump’s characterization of the alleged plot or said how long the suspects had been under surveillance.
“We are in the early stages of an investigation, and five men remain in custody,” Deputy Assistant Commissioner Vicki Evans, the senior national coordinator for Counter Terrorism Policing, said.
Police said the immediate incident has been contained, but the investigation remains ongoing.
