British counterterrorism officers have made a series of arrests in London and surrounding areas, focusing on two distinct investigations involving eight men, including seven Iranians. The first operation saw four Iranian nationals and one other individual captured on suspicion of preparing to execute a terrorist act against a specific yet undisclosed site. London’s Metropolitan Police reported that this ongoing investigation is described as “fast-moving,” with police closely coordinating with the targeted location to ensure safety and security. Dominic Murphy, head of the Counter Terrorism Command, indicated that considerable efforts are being made to determine the motives behind these activities and any additional risks they may pose to the public.

Eight men, seven of whom are Iranian nationals, have been detained by British counterterrorism forces in significant operations aimed at thwarting potential terrorist activities.
In a second wave, three more Iranian men were arrested in separate locations throughout London, although their case is not directly associated with the earlier investigation. They were apprehended following the enforcement of the National Security Act 2023, which aims to bolster protections against hostile actions in the UK. Home Secretary Yvette Cooper termed these arrests as indicators of the ongoing need for an adaptive response to national threats. In light of these events, MI5's director Ken McCallum has previously highlighted the increasing dangers posed by Iran, citing 20 Iranian-backed plots since early 2022 potentially threatening UK citizens. Authorities are committed to updating the public as the investigations progress while maintaining operational confidentiality.
