British officials are weighing whether to warn publicly that Iran now has US military targets in Europe on its mind, following a confused incident near RAF Fairford that led to the withdrawal of American B-1 bombers from the Gloucestershire base. While scepticism remains about Iran’s capability to carry out a drone raid on a secure facility, MI5 accepts that the Islamic Revolutionary Guard Corps (IRGC) has stepped up efforts to target the Jewish community in the UK.

The incident at RAF Fairford on 27 September saw five men from London drive to the nearby village of Whelford in three white vans shortly after midnight. One of them called 999 as they did so. All five were arrested and released on police bail a day later after no explosives were found. Two more men have since been arrested on suspicion of terror offences and also released on bail.

Prime Minister Andy Burnham said there were “strong indications” Iran played a part. Met Police chief Mark Rowley indicated that more progress on the investigation would follow.

A week after the incident, the US decided to withdraw the 12 B-1 bombers it had stationed at Fairford, with leaks to US media suggesting a fear of a Ukraine-style drone attack. The base had been used by US bombers making attack runs into Iran in the spring and early summer, authorised by the former prime minister Keir Starmer.

Lord Ricketts, a former UK national security adviser, said: “Iran has a track record of planning and carrying out attacks especially on opponents of the regime in the UK. Given the use of Fairford by US bombers, it's only prudent to assume that they would see an interest in attacking a wider range of targets, whatever their involvement in the Fairford incident.”

Dr Antonio Giustozzi, a terrorism specialist with the Royal United Services Institute, suggested the drive to the village may have been a “feint” to hint at what could happen. He expressed scepticism that Iran could pose a real military threat, noting that piloting first-person view drones requires days or weeks of training and that bringing military-grade explosive to the UK would be extremely difficult.

MI5 has accepted that the IRGC has sought to coordinate attacks on the Jewish community in the UK and Europe, starting in March with a string of arson attacks on synagogues. This marks a significant escalation from the regime’s longstanding campaign of assassination plots against critics overseas.

Analysis

Why This Matters

The incident signals that Iran may be willing to attempt attacks on US military assets in Europe, even if its capability is in doubt.
The threat to the UK has escalated from assassination plots against individuals to potential attacks on critical infrastructure and communities.
The response will shape the UK’s relationship with the US and its posture toward Iran at a time of heightened tensions.

Background

Britain was peripherally involved in the US-Israeli bombing campaign against Iran earlier this year, allowing US bombers to operate from RAF Fairford for attack runs. The IRGC has long run operations inside the UK, using criminal gangs to target regime opponents. Since March, the group has shifted to inciting and coordinating arson attacks on synagogues, marking a new phase in its campaign.

Key Perspectives

UK government and security services: The prime minister has pointed to Iranian involvement, and the Met Police chief promises more progress. MI5 accepts the IRGC is actively targeting Jewish communities. US military: The decision to withdraw B-1 bombers suggests genuine concern about a physical attack on the base, even if no plot was uncovered. Sceptics (experts and analysts): Some specialists doubt Iran can execute a drone attack on a secure airbase. The arrested men were released without charge, and the lack of explosives suggests the threat may have been a feint rather than a genuine operation.

What to Watch

The outcome of the police investigation and whether further arrests or charges are made.
Whether the US redeploys bombers to alternative bases in Europe or the Middle East.
Any public warning from Western officials about the threat to US military targets in Europe.
Further intelligence on IRGC activity in the UK, particularly against Jewish targets.
