Britain should strengthen counterintelligence protections around military bases used for US operations

British police released five suspects on restrictive bail while investigating possible foreign-state involvement in the suspected RAF Fairford plot. US officials asserted that a foreign actor was involved and suggested Iran as a possibility, but disclosed no supporting evidence; Iran denied involvement. Police reportedly found petrol but no viable explosive device.

Andy Burnham said the suspected Fairford plot was highly likely coordinated in Iran and almost certainly directed by the Revolutionary Guards. Iran denied involvement and requested supporting evidence. The statement constitutes an official intelligence assessment, rather than a judicial finding.
