Men arrested and residents evacuated following security incident at UK air base

A spokesperson for the US Air Force declined to 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 warned the UK 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.
