Tehran denies role in UK air base incident as Britain recalls Iranian envoy

LONDON, 13 OCTOBER 2026 —

British Prime Minister Andy Burnham on Monday formally accused Iran’s Islamic Revolutionary Guard Corps (IRGC) of orchestrating a terror-related incident at RAF Fairford air base in September, prompting Tehran to deny any involvement and London to summon Iran’s ambassador for urgent talks.

The incident unfolded on September 27, when five British men were arrested near Fairford on suspicion of terrorism and explosive offenses. US officials, including President Donald Trump, later confirmed that intelligence indicated an Iran-linked threat had prompted the withdrawal of US bombers from the base.

While police found petrol in vans seized during the arrests, no viable explosives were recovered, though British authorities—including Home Secretary Shabana Mahmood—have insisted a foreign state actor was behind the plot. Mahmood revealed in Parliament that a known individual based in Iran was believed to be the mastermind, though the individual was not named.

Iran’s denial came through its ambassador to Britain, Seyed Ali Mousavi, who told the Iranian state news agency IRNA that Tehran had “no involvement” in the matter.

Mousavi challenged the UK to present evidence, stating: “If the British government possesses any documents or evidence to support its claims, it should present them.” The British Foreign Office responded by summoning the Iranian ambassador for discussions, while Foreign Minister Ed Miliband reiterated London’s stance that the IRGC remains a persistent threat.

The Fairford incident is the latest in a series of alleged Iranian-backed plots targeting British soil. Last year, the UK government reported 20 credible threats linked to Iran, including attempts to assassinate or kidnap individuals. In July, Britain expanded its counterterrorism measures by banning support for the IRGC and the militant group Harakat Ashab al-Yamin al-Islamiya (HAYI), which claimed responsibility for attacks on Jewish and Israeli-linked sites earlier this year.

The UK also sanctioned two Iranian nationals: Ruhollah Bazghandi, identified as the IRGC’s head of counterespionage operations, and Shahram Ali Reza Tamarzadeh Jakki, a facilitator for the Zindashti criminal network, which has been accused of involvement in plots against Iranian dissidents.

The UK’s accusations align with a broader international condemnation of Iran’s alleged hybrid warfare tactics. A statement from the foreign ministries of nearly 30 countries, including the US, Canada, France, and Germany, condemned Iran’s use of “violent attacks, including lethal plotting, arson, sabotage, cyber-attacks, and other hybrid activities” against Western interests.

The UK government has framed the Fairford incident as further proof of the IRGC’s willingness to project hostile activity beyond its borders through covert networks and proxy actors.

Burnham vowed a tough response, warning that the UK would “crack down on Iran’s use of criminal networks” and impose additional sanctions to restrict the IRGC’s capacity to operate. The five men initially arrested near Fairford were later released without charge under stringent police bail conditions, though two others—including a British-Iranian national—were also released after investigations.

The lack of concrete evidence in the case has not deterred British officials from attributing the plot to Iranian state actors, setting the stage for potential further diplomatic or legal action.

The UK’s stance reflects its long-standing policy of treating Iranian-backed threats as a national security priority, with Burnham emphasizing that London would not tolerate such activities on its soil. The next steps remain unclear, but the summoning of Iran’s ambassador and the threat of new sanctions suggest a hardening of Britain’s position ahead of potential retaliatory measures.
