Britain has authorised the United States to use RAF Fairford to conduct strikes against Iranian missile sites targeting vessels in the Strait of Hormuz.
Armed police were seen blocking access to the main entrance of the airbase, according to a Reuters eyewitness. Around 30 emergency vehicles, including police cars, ambulances and fire engines, were deployed in the nearby village of Fairford.
Gloucestershire Police said several properties in the Whelford area were being evacuated after authorities declared a major incident. The move followed the arrest of several men on suspicion of offences under the Explosives Act.
“The Army’s specialist explosive ordnance disposal team are currently examining a number of vehicles,” police said.
The US Air Force declined to provide details about specific security measures at the base.
A spokesperson for the US Air Force said the 501st Combat Support Wing and other US units based in Britain remained vigilant and would take appropriate measures to protect US personnel, civilians, contractors and their families.
The spokesperson added that officials were continuously assessing security risks and adjusting protective measures for military installations and personnel when necessary.
In July, Britain said its armed forces were prepared to defend the country against potential attacks after Iran’s Revolutionary Guards warned against allowing US bombers to operate from RAF Fairford.
The British government has also warned critical infrastructure providers about potential threats from Russia, amid growing concerns over sabotage and cyberattacks. Moscow has denied accusations that it is conducting hybrid attacks against Western countries.
