US prosecutors have charged three men in a case alleging that an Iran-aligned network was involved in attacks in London and a separate plot involving an airbase in Gloucestershire.
The eight-count superseding indictment was unsealed on Tuesday, 10 November. It names Mohammad Baqer Saad Dawood al-Saadi, Mohsen Mohajeri and Mohammad Ali al-Hassani. The charges are allegations, not findings of guilt, and all three are presumed innocent unless proven guilty in court.
Prosecutors say the men conspired to support Iran’s Islamic Revolutionary Guard Corps and the Iraqi group Kata’ib Hizballah. Both organisations are designated as foreign terrorist organisations by the United States. The indictment also includes allegations of conspiracy to bomb a place of public use and financing terrorism.
Allegations involving London
According to the US Department of Justice, the alleged network was associated with a group using the name Harakat Ashab al-Yamin al-Islamiya. The department says the group claimed responsibility for 18 attacks in Europe in spring 2026, including seven in the UK. A claim of responsibility is not, by itself, proof of who carried out an attack.
One allegation concerns an attack on a London synagogue on or around 18 April. Prosecutors say al-Hassani took part in a video call with a person carrying out the attack and directed that person’s actions. The department alleges that an improvised explosive device was thrown at the building. Its description does not name the synagogue.
The US statement also refers to the stabbing of two Jewish men in London as part of the alleged campaign. It does not name the neighbourhood or identify the men involved.
Two Jewish men were stabbed in Golders Green, north London, on 29 April. In a British court case arising from those stabbings, Essa Suleiman pleaded not guilty to attempted murder. In September, prosecutors told the court that a review had found insufficient evidence to say the Golders Green stabbings had a terrorist connection.
The US announcement does not explicitly identify the Golders Green incident as the stabbing it describes. Its allegations and the British prosecutors’ assessment should therefore not be treated as resolving one another. The British proceedings involve a different defendant from the three men named in the US indictment.
A new stage in the US case
The November indictment is a fresh stage in a prosecution, not a report that the London incidents happened this week. US authorities brought earlier charges against al-Saadi in May, including allegations concerning attacks in Europe. He pleaded not guilty to those earlier charges in June.
The superseding indictment names two additional defendants and sets out allegations concerning RAF Fairford, where US military personnel and aircraft were based. Prosecutors allege that al-Hassani arranged preparations for an attack on the base and that al-Saadi passed coded messages to associates while in custody in New York.
In the early hours of 27 September, British authorities recovered three vans and arrested their occupants near the base. US prosecutors say some of the vans contained barrels of fuel. Iran’s embassy in London has denied Iranian involvement in the Fairford incident; that denial addresses the airbase incident, not every allegation in the US case.
Al-Saadi was in US custody awaiting trial on the earlier charges. Mohajeri and al-Hassani were not in US custody when the new indictment was announced. The allegations remain to be tested in court, and the new charges do not establish responsibility for any of the incidents described by prosecutors.
