UK Prime Minister Andy Burnham has attributed threats made against RAF Fairford to Iran's Islamic Revolutionary Guard Corps (IRGC), calling their involvement "almost certainly" responsible. Burnham told MPs that the UK would pursue additional sanctions against both Tehran and the IRGC following the incident, which occurred late last month.
The assessment marks the firmest attribution of responsibility made by the UK government since the episode took place. Police have investigated the matter for over a fortnight but have not charged anyone in connection with the threats.
The source material does not specify the nature of the threats, the circumstances of the incident, the timing of the police investigation, what prompted the UK's assessment, or what additional sanctions the government plans to impose. The Guardian report indicates the episode remains ambiguous despite sustained investigative effort.
