VIDEO | UK Prime Minister Andy Burnham says the incident at RAF Fairford in September was "almost certainly" directed by Iran's Islamic Revolutionary Guard Corps (IRGC).

The incident occurred in the early hours of 27 September, when police responded to reports of suspicious activity involving three vans near the base in Gloucestershire and arrested five men on suspicion of terrorism and explosives-related offences.

Nearby properties were evacuated during the investigation, and police later confirmed that petrol had been found in the vehicles but no explosives. Seven men have since been arrested in connection with the investigation and released on bail, with no charges announced.

No evidence has been provided by UK authorities establishing a link between the incident and the IRGC, and Burnham has not cited intelligence or other material supporting his assertion.
