Police declare major incident at UK's Fairford air base, used by US air forces

Around 30 emergency vehicles, including police cars, ambulances and fire engines, were stationed in the village of Fairford near the base. "A number of properties are currently being evacuated in the Whelford area following the declaration of a major incident.

It follows the arrest of several men on suspicion of offences under the Explosives Act," Gloucestershire police said in a statement, referring to a village near the air base. "The Army's specialist explosive ordnance disposal team are currently examining a number of vehicles.

"A spokesperson for the US Air Force said they would not discuss specific force protection measures. "The 501st Combat Support Wing and our fellow UK-based Wings remain vigilant and will take appropriate actions to ensure the safety and security of our US service members, civilians, contractors, and their families," the spokesperson said.

"We constantly assess a variety of factors that determine what measures we institute or modify to protect our installations, our people and their families. "Britain said in July its armed forces were ready to protect the country from any attack after Iran's Revolutionary Guards issued a warning not to allow US bombers to fly from Fairford.

British ministers have also briefed providers of critical infrastructure on the threat posed by Russia, with the government increasingly concerned about possible sabotage operations and cyberattacks. Russia denies mounting hybrid attacks on Western nations.
