Iran’s Expanding Hybrid Campaign Targets UK Military Sites, Says MI5 Chief
By Drooid · · How we work
Core Event
He cited the RAF Fairford incident on September 27, 2026—when three vans were found near the U.S.-run air base and police discovered only gasoline—to illustrate a “major shift” in Iranian tactics. McCallum said the plot was “not unique” and that Iran-linked operations have produced more than 50 arrests in the United Kingdom over the past year.
Background & Context
Iran has long been accused by British authorities of using criminal proxies to target Jewish communities, Iranian media outlets, and Israeli interests on UK soil. The recent focus on a strategic military installation marks a departure from earlier sabotage and arson attacks. The UK’s security environment has been described by McCallum as a “new era of national security,” comparable in scale to the post-9/11 period.
Data & Statistics
- Arrests: Over the last 12 months, MI5 investigations have led to more than 50 arrests linked to Iranian operations.
Official Statements & Responses
- Ken McCallum emphasized that the Fairford episode “is not unique” and warned that Iran’s use of “criminal proxies” could evolve toward more sophisticated attacks.
- Prime Minister Andy Burnham told Parliament that the plot was “almost certainly directed” by Iran’s Islamic Revolutionary Guard Corps (IRGC).
- Russian officials denied involvement in hybrid activities across Europe.
- Iranian authorities rejected the allegations, stating that any base used to strike Iranian territory is a legitimate target.
On-the-Ground Reports
Local police and army bomb-disposal units responded to the September 27 incident, evacuating nearby residents and searching the three vans. The investigation uncovered only gasoline, with no explosives or weaponised material found. Seven men in their 20s, including a dual British-Iranian national, were arrested and later released on bail.
Conflicting Reports & Gaps
- No public evidence has confirmed the presence of explosives or advanced drone technology at the Fairford site.
- Details of the vans: Authorities have not disclosed the identity of the “third party” allegedly directing the two Liverpool-based suspects charged with planning a chlorine-based bomb, leaving the full scope of the network unclear.

Why It Matters
Targeting military infrastructure raises the stakes of Iran’s hybrid warfare and could draw the United Kingdom deeper into the broader Iran-U.S. contest. Increased arrests and expanded MI5 resources indicate a heightened domestic security posture, while AI is emerging as a tool for both attackers and defenders.
What’s Next
MI5 has established an AI Threat Assessment Centre to monitor emerging risks, and the UK government continues to evaluate the security of critical sites such as RAF Fairford. Ongoing investigations are expected to clarify the extent of Iranian involvement and determine whether further protective measures for military installations will be required.
