British police arrest men over explosives near U.S. air base RAF Fairford

British police declared a major incident on Sunday, 27 September 2026, and evacuated residents from Whelford, a village in Gloucestershire near RAF Fairford, following the arrest of several men on suspicion of offenses under the Explosives Act. Counter-terrorism police are leading the investigation. An Army bomb disposal team examined multiple vehicles at the scene, and residents were relocated to a nearby leisure centre. Police stated the incident is contained, though authorities have not confirmed whether the arrests are directly linked to the air base.

RAF Fairford, located approximately two miles from Whelford, hosts U.S. Air Force assets, including the 501st Combat Support Wing. Since February 2026, the base has been used by the U.S. military for operations targeting Iran following the start of the U.S.-Israeli military actions against Iran on 28 February. The British government authorized this use to conduct strikes on Iranian missile sites. Security measures at the base had been significantly increased in recent days, with armed police and roadblocks limiting access.

A U.S. Air Force spokesperson stated that personnel at RAF Fairford "remain vigilant" and would take appropriate actions to ensure the safety of service members, civilians, contractors, and families, but would not discuss specific force protection measures for security reasons. British Prime Minister Andy Burnham was kept informed of developments. Defence Secretary Wes Streeting confirmed the situation was being handled and thanked emergency services and armed forces personnel.

Eyewitnesses reported approximately 30 emergency vehicles, including police cars, ambulances, and fire engines, deployed to the area. Armed police were observed blocking access to the main gate of the base. The incident reflects heightened security concerns in the region, as Iran's Revolutionary Guards had issued warnings in July against allowing U.S. bombers to operate from British bases. British ministers have also been briefed on threats posed by Russia, citing concerns about potential sabotage operations and cyberattacks targeting critical infrastructure.
