Three Iranian men have been charged under the UK’s National Security Act on suspicion of conduct likely to assist Iran.
Mostafa Sepahvand, 39, Farhad Javadi Manesh, 44, and Shapoor Qalehali Khani Noori, 55 were arrested on 3 May.
The charges relate to a period between 14 August 2024 and 16 February 2025, police said.
Cdr Dominic Murphy, from the Metropolitan Police’s Counter Terrorism Command, says the charges come following “a very complex and fast-moving investigation”.
The three men have been remanded in custody and are due to appear at Westminster Magistrates’ Court on Saturday.
