UK police have arrested five men near a US air base who are being held on suspicion of preparing a terrorist act, per the AP. Police said the situation appeared to be "contained" but did not confirm that the arrests were linked to the base, RAF Fairford. The base hosts the headquarters of the US Air Force's 501st Combat Support Wing and the 420th Air Base Squadron, and it's been used by American forces for strikes during the war with Iran. The site is near the village of Whelford, about 90 minutes outside London, per NBC News.
Footage from Sky News appeared to show a bomb-disposal robot roaming between three white trucks. A 400-meter cordon has been put in place around the three vehicles, and about 85 households have been evacuated. Gloucestershire police said officers responded early Sunday to reports of suspicious vehicles moving toward the base, then arrested five men "on suspicion of committing offenses under the Explosives Act." No details were immediately provided about the suspects.
