The United Kingdom has raised its national terrorism threat level from “substantial” to “severe,” following a stabbing attack targeting Jewish victims in north London. The move signals that an
attack is considered highly likely in the coming months and reflects what officials describe as a broader escalation in extremist threats.
The decision, made independently by the Joint Terrorism Analysis Centre, comes a day after two Jewish men were stabbed in the Golders Green area. Authorities emphasized that the change in threat level was based on a combination of recent intelligence and a sustained rise in security risks, rather than the single incident alone.
Prime Minister Keir Starmer said the attack had intensified fears within Britain’s Jewish community, describing a climate in which many feel unsafe expressing their identity or practicing their religion openly.
“People are scared—to go to synagogue, to attend university, to send their children to school, or even to say they are Jewish,” Starmer said in a televised address. He pledged increased police presence in affected areas, tougher action against antisemitism, and new legislation to counter threats linked to foreign states.
Security officials say the UK faces a complex and evolving threat landscape. Counter-terrorism policing chief Laurence Taylor warned of heightened risks to Jewish and Israeli individuals and institutions, alongside concerns over hostile activity tied to international actors.
Home Secretary Shabana Mahmood said the updated threat level reflects both immediate risks and longer-term trends, including the influence of foreign states accused of fuelling violence. The government has pointed to Iran as one such actor, alleging links to recent hostile activities—claims Tehran denies.
The suspect in the Golders Green attack, a 45-year-old British national, reportedly had a history of violent offenses and mental health issues. Police confirmed he had previously been referred to a government counter-radicalisation programme.
The government also announced plans to fast-track legislation enabling authorities to prosecute individuals acting on behalf of foreign states in the same way as spies. Additional measures include expanding powers to shut down organizations accused of promoting extremism and targeting individuals spreading hate speech.
Tensions have also been exacerbated by ongoing pro-Palestinian demonstrations across the UK, which have drawn criticism from some Jewish groups who say such protests have contributed to a rise in antisemitic incidents. Starmer condemned slogans perceived as inciting violence, calling them “extreme racism” and warning that they should be subject to legal consequences.
