The Crown Prosecution Service (CPS) said Abdulkarim, from London, is charged with assisting a foreign intelligence service, which counter-terrorism police believe to be Iran. Essghir, also from London, is charged with entering a prohibited place for a purpose prejudicial to the UK on 22 August.
Essghir was first arrested near the Gloucestershire airbase on 27 September, when three suspicious vans were stopped carrying petrol. Police declared a major incident, evacuated residents and searched for explosives, but found none. Abdulkarim was arrested in the past week. Both men were re-arrested on 20 October.
Assistant Commissioner Laurence Taylor, head of National Counter Terrorism Policing, said: “In this case, we believe that country to be Iran.” He confirmed Essghir was charged under Section 4 of the National Security Act 2023 and Abdulkarim under Section 3.
Five other men arrested during the original investigation remain on police bail. A 25-year-old UK-Iranian dual national re-arrested last week has been released without charge but remains on bail from his first arrest.
The incident led US President Donald Trump to withdraw US bomber aircraft from the base, saying: “Rather than tempting the enemy, we'll capture the enemy and beat the enemy … why should we leave him there?”
British Prime Minister Andy Burnham called the activity at RAF Fairford “almost certainly” directed by Iran’s Revolutionary Guard. Iran has denied involvement.
Frank Ferguson, chief crown prosecutor for the CPS Special Crime and Counter Terrorism Division, said: “We will continue to work closely with our partners as this complex investigation continues.”
