Terror plot foiled: counter-terror police arrest 12 over alleged far-right threat to Islamic gathering

Major security operation launched after intelligence suggested UK’s largest Muslim congregation could be targeted

British counter-terrorism police have arrested 12 people in a major nationwide operation over an alleged extreme right-wing terrorism plot targeting one of the United Kingdom’s largest Islamic religious gatherings, in what officials say was a swift intervention to protect thousands of worshippers.

The arrests followed an intelligence-led investigation into a suspected threat against the UK Ijtima, an annual Islamic congregation held at Shrubland Hall in Suffolk. The event attracted around 10,000 worshippers from across Britain and overseas over the weekend.

Police advised organisers to conclude the gathering earlier than planned after receiving intelligence indicating a potential threat. The event ended without incident, with all attendees leaving the venue safely. Authorities have confirmed there is currently no wider threat to the public.

Counter Terrorism Policing London said eight men were arrested under the Terrorism Act 2000 on suspicion of terrorism-related offences. Three other men were detained on suspicion of conspiracy to murder, while a woman was arrested on suspicion of assisting an offender. The suspects, aged between 27 and 82, were detained during coordinated raids across London, Surrey, Essex, Greater Manchester, Suffolk and other parts of England. Searches of several properties remain ongoing.

Commander Helen Flanagan, head of Counter Terrorism Policing London, said officers acted rapidly after intelligence identified what was believed to be a credible threat. She praised the close cooperation between police forces and intelligence agencies, adding that public safety remained the overriding priority throughout the operation.

The investigation has once again highlighted the growing concern over violent far-right extremism in Britain. Security officials have repeatedly warned that extreme right-wing terrorism continues to pose a significant domestic threat, with online radicalisation increasingly driving extremist activity.

Home Secretary Shabana Mahmood described the alleged plot as “deeply concerning” and commended the professionalism of counter-terrorism officers. She said the operation demonstrated the government’s determination to protect every community from terrorism, regardless of ideology.

Muslim community leaders welcomed the swift police action, saying the safety of worshippers had been paramount. They also urged people not to allow extremists to divide communities, calling for unity and vigilance against all forms of hatred.

No charges have yet been filed, and detectives say the investigation remains at an early stage. Officers continue to examine evidence seized during the raids, while further arrests have not been ruled out.

The operation is being regarded as one of the most significant counter-terrorism investigations into alleged far-right extremism in recent years, underlining the continued vigilance of Britain’s security services in safeguarding places of worship and public events.
