UK Sanctions Iran Over Suspected Plot Near Air Base; Allies Back Findings

A security incident near the Royal Air Force Fairford base in Gloucestershire, England, on September 29, 2025, led to the arrest of five men in their 20s on suspicion of explosives offenses and preparing an act of terror. Authorities responded to reports of three suspicious vans in the village of Welford, near the base, which is also used by the U.S. Air Force. Police and bomb disposal units were deployed, and residents from dozens of homes were evacuated while movement in the area was restricted.

Initial concerns about potential car bombs were not substantiated, as no explosives or improvised devices were found. However, gasoline was discovered in the vehicles, leading investigators to explore the possibility of a planned arson attack. Reports suggest that Israeli security services provided the initial warning about the suspicious vehicles.

On October 10, 2026, the British government announced its assessment that Iran's Islamic Revolutionary Guard Corps (IRGC) was involved in the incident. In response, the UK imposed sanctions on two Iranian individuals, including a senior IRGC official.

In a joint statement, the UK, France, Spain, Greece, the United States, and other nations acknowledged Britain's findings regarding Iranian involvement. They warned against hostile activities by the IRGC outside Iran's borders, stating that the incident highlights the IRGC's continued willingness to conduct such operations internationally. These actions and statements are part of a broader diplomatic effort against Iran's activities abroad, amid concerns about espionage and threats to British and international interests.
