British authorities evacuate Whelford residents following major security incident

British authorities evacuated buildings and deployed military bomb disposal teams over a "major incident" in the town of Whelford on Sunday morning.

The town is located near the Fairford air base, which is used by the US military. Around 30 emergency vehicles were seen in the area, including police cars, ambulances, and fire engines.

Counter-terrorism police were involved in the investigation.

Bomb disposal units examining three 'suspicious vehicles'

Police said they had received a call earlier on Sunday about "three suspicious vehicles" heading to the base.

"Armed officers responded and subsequently arrested five men in the Whelford area," assistant chief constable Richard Ocone told reporters.

He added that a cordon of 400 meters, or approximately 1/4 of a mile, has been put in place around the vehicles "while the army's explosive ordinance disposal unit examine them."

"As a precaution, around 85 households have been advised to evacuate while these examinations take place," Ocone said.

He added that some of the evacuees were taken to a nearby leisure center.

The Gloucestershire police representative also asked the public "not to speculate" but follow official channels instead.

Previously, the authorities said that several men were "arrested on suspicion of offences the ​Explosives Act."

"A cordon is currently in place but we'd like to reassure people that we believe this incident is contained," British police said.

Officials stay tight-lipped

A spokesperson for ​the US Air Force refused to discuss specific steps when contacted by the Reuters news agency, saying only that both US and British forces "remain vigilant and will take ⁠appropriate ​actions to ensure the safety and security of our ​US service members, civilians, contractors, and their families."

The background for the incident was not immediately clear.

The UK has allowed the US to use Fairford for its war against Iran, with Iran's Revolutionary Guards warning UK officials against the move this summer. The evacuations also come at a time of heightened tensions in Northern Ireland, and less than two months after Germany discovered an explosive-laden drone at the Leipzig airport, which its authorities attributed to Russia.
