UK Prime Minister Says Iran's IRGC Almost Certainly Directed Suspected RAF Fairford Plot. Seven Arrested, None Charged

British Prime Minister Andy Burnham said Monday that a suspected plot against RAF Fairford was "highly likely to have been coordinated in Iran, almost certainly directed by Iran's Islamic Revolutionary Guard."

He made the statement to lawmakers. "We will not tolerate these threats on our soil," he said.

Burnham did not release the evidence behind the assessment. As of today, Oct. 13, no one has been charged.

What police found

The case began in the early hours of Sept. 27, when five men were arrested near the base in three vans on suspicion of terrorism and explosives offenses. Scores of nearby residents were evacuated from their homes while armed police and army bomb-disposal teams searched the area.

Police later said the vans held a quantity of accelerant, gasoline, but no explosives. Detectives said they were weighing whether a foreign state was involved.

Two more men were arrested later, one of them a dual U.K.-Iranian citizen. Police said six of the seven are British nationals. All are in their 20s, none has been publicly identified, and all have been released on bail.

The drone allegation

The larger claim comes from U.S. and European officials, who told the Wall Street Journal that the Fairford alert was driven by fears of a "potentially complex drone attack" ordered by the IRGC. According to the Journal, the drone strike was one piece of a broader plan to destroy aircraft and kill personnel, including American pilots. The Journal also reported that U.S. military officials in Europe were warned in late September about a possible vehicle-borne explosive attack.

Axios, citing U.S. officials, reported intelligence pointing to a possible drone attack launched from British soil. Those officials have not been named, and neither the U.S. nor the U.K. government has publicly laid out the drone evidence.

The physical evidence police have described so far is gasoline in vans. That does not match the drone-and-explosives picture from the anonymous officials, and the government has not explained how the pieces fit together.

Bombers out, officials split on why

The U.S. pulled roughly a dozen B-1 bombers from Fairford, and the Pentagon says they have all returned to home stations in the United States. It added that its B-1, B-2 and B-52 fleets can still conduct global precision strikes from American soil.

The explanations were not uniform at first. Secretary of State Marco Rubio emphasized that military aircraft routinely rotate between bases and declined to tie the move to the suspected plot. Vice President JD Vance said War Secretary Pete Hegseth ordered the move "out of an abundance of caution," adding that the administration believed "with some confidence" that Iran was continuing a long pattern of terrorism against the U.S. and others.

President Trump then said outright that the bombers "didn't fly out by accident." "There were some threats," he said, and the people behind them "would be linked to Iran." Asked whether Iran had brought combat drones into Britain, he said: "I can't tell you that, but if they did, they'll suffer greatly."

Trump has also left open further action against Iran. That follows weeks of stalled peace talks and an ongoing war in which U.S. bombers have used Fairford to strike Iranian missiles and launch sites.

Iran's denial and London's response

Iran rejects the accusation. Tehran has called it "unfounded and malicious speculations." Iran's ambassador, summoned by the British government on Monday, repeated that Iran had no part in the suspected plot and urged the U.K. to produce evidence.

Iran has also said before that it considers any base used to attack its territory a legitimate target. That statement is not an admission about Fairford, but it is on the record.

London did not wait for charges. The U.K. added two Iranians to its sanctions list, including the IRGC's head of counterespionage operations. The government says the pair were involved in espionage and attacks on Iran's behalf in Europe and the U.S.

Burnham also promised to "crack down on Iran's use of criminal networks" and to bring "further sanctions to restrict the capacity of Iran and the IRGC to do us harm."

The wider pattern

The British government points to a series of incidents. Officials say Iran-linked local proxies have been behind arson and other attacks on the U.S., Britain and other countries, many aimed at Jewish communities. In July, Britain used new state-threat powers to ban support for the IRGC and a linked group accused of attacks on Jewish and Israeli sites and on Persian-language media.

Britain permitted the U.S. to use Fairford for what it called defensive strikes after Iranian attacks on U.K. interests and allies in the Gulf. That decision put the base in the war's line of fire.

It is unclear whether the seven suspects will be charged, or what the Crown Prosecution Service can show about any link to Tehran. The released suspects remain on bail under what police called stringent conditions, and Burnham has said more sanctions are coming.
