Prime Minister Andy Burnham said the UK govt believes the Iranian state was behind a security incident at an airbase that’s used by the US to launch strikes on the country.Five men remain under investigation by police after being arrested on Sunday on suspicion of preparing a terrorist act at RAF Fairford in Gloucestershire, England. While investigators said they didn’t find explosive devices at the scene, they did recover a quantity of fuel. The men were bailed as the probe continues.Asked by the BBC on Wednesday whether a foreign actor was involved, Burnham replied: “We believe so. There are strong indications that Iran played a part in what happened over the weekend at RAF Fairford, but of course it remains an ongoing, complex and serious police investigation.”“Of course, we are working closely with our colleagues in the United States of America,” he added.Iranian Embassy in London on Monday had said that it “categorically rejects and strongly condemns” what it dismissed as “unfounded and malicious” attempts to link the case to Iran. Such speculation would “serve no purpose other than to fuel Iranophobia propaganda in the UK,” the embassy said in a statement posted on X. RAF Fairford serves as the preferred forward operating base for bomber aircraft in Europe for US Air Force Global Strike Command.
