UNITED KINGDOM — SITUATION REPORT

28 September 2026 07:29 ZULU

EXECUTIVE SUMMARY

Five individuals were arrested near RAF Fairford on 27 September on suspicion of preparing a terrorist act involving explosives, targeting a UK airbase hosting US bombers. This incident, which British counter-terrorism police are investigating for potential Iranian links, occurred amidst ongoing protests by Palestine Action at the Labour Party conference, resulting in multiple arrests.

KEY DEVELOPMENTS (past 24 hours)

Foiled Attack at RAF Fairford: On 27 September, five men were arrested near RAF Fairford, Gloucestershire, on suspicion of offenses under the Explosives Act and preparation of a terrorist act. The arrests followed a public report of three suspicious vehicles near the base, which hosts US B-1B Lancer bombers used for strikes on Iran. Explosive ordnance disposal teams were deployed, and a 400-meter cordon led to the evacuation of 85 households in the village of Whelford. Counter-terrorism police are investigating a potential link to Iran, citing previous warnings from Tehran that bases used for aggression against Iran would be legitimate targets. Former President Trump praised the joint US-UK efforts in foiling the plot.
Palestine Action Protests: More than 50 Palestine Action supporters were arrested outside the Labour Party conference in Liverpool on 27 September. Protesters displayed signs supporting Palestine Action, a proscribed organization, leading to arrests under the Terrorism Act. Amnesty International has criticized these arrests as an attack on freedom of expression.

THREAT ASSESSMENT

The national terrorism threat level in the UK remains at SEVERE, indicating that a terrorist attack is highly likely. The foiled plot at RAF Fairford underscores the persistent and evolving threat from various actors, including those potentially linked to state-sponsored entities. US-associated facilities and personnel in the UK are at heightened risk.

DIPLOMATIC STATUS

The UK maintains close security cooperation with the United States, as evidenced by the joint response to the RAF Fairford incident. The UK government, under Prime Minister Andy Burnham, has recently recognized the State of Palestine and is pursuing closer ties with the European Union on defense and security matters.

OUTLOOK (24–72 hours)

Investigations into the RAF Fairford plot are ongoing, with authorities focused on identifying motives and any broader networks, particularly potential foreign state involvement. Increased security measures are likely to remain in place at military installations. Further arrests related to the Palestine Action protests are possible as the Labour Party conference continues.
