Three Iranian men—Mostafa Sepahvand, Farhad Javadi Manesh, and Shapoor Qalehali Khani Noori—have been charged under the UK’s National Security Act for conduct likely to assist Iran, following their arrest on May 3. They face serious allegations, including engaging in surveillance and reconnaissance with intentions of committing violence against individuals in the UK, with all three remanded in custody until their court appearance. The investigation, described as complex and fast-moving by Cdr Dominic Murphy of the Metropolitan Police’s Counter Terrorism Command, reflects significant counter-terrorism operations in recent years.
