85 households in Whelford, about 1.6 km from RAF Fairford, were evacuated in the early hours of Sunday after authorities were alerted to suspicious vehicles, according to AFP.

Police arrested five men on suspicion of preparing a terrorist act near the base, without confirming the nature or source of the threat, according to AFP. In March, the United Kingdom authorized the US to use Fairford for specific defensive operations against Iran, and since then US bombers have used the runway, according to AFP.
