UK Prime Minister Andy Burnham told Parliament it is highly likely the threats against RAF Fairford were coordinated in Iran and almost certainly directed by the Islamic Revolutionary Guard Corps (IRGC).

Burnham said the UK would bring further sanctions against Tehran and the IRGC as a result, with more information to follow in an update from Home Secretary Shabana Mahmood. Five men from London drove to Whelford, a village next to a base used by the US air force, in three white vans shortly after midnight on 27 September. They were released on police bail a day later after no bombs or explosives were found. A week later, the US withdrew 12 B-1 bombers from the base, amid reports of concern about a possible drone attack on a base used to attack Iran during the Middle East war in the spring and summer.
