UK Terror Adviser Calls Antisemitic Attacks 'National Security Emergency'

Two Jewish men were stabbed in Wednesday's attack; two people were killed and three seriously injured in an October 2025 car ramming and stabbing attack outside a Manchester synagogue.
If you are visibly Jewish, you're not safe
Chief Rabbi Ephraim Mirvis's assessment following the stabbing attack in north London.

In the weeks and months following a sustained wave of violence against Jewish communities across Britain, a stabbing attack on two Jewish men in north London became the moment the government could no longer hold its language at arm's length. The UK raised its terrorism threat level to severe for the first time in four years, and the government's own counterterrorism adviser named antisemitism a national security emergency of a magnitude not seen in nearly a decade. What has emerged is not a single crisis but a layered one — foreign state actors, domestic extremists, and a cultural erosion of safety converging on a community increasingly uncertain it can live an ordinary life in its own country.

  • A 45-year-old British national stabbed two Jewish men in Golders Green on Wednesday, and police classified it as terrorism before the day was out — the latest in a pattern that now includes car rammings, synagogue arsons, and suspected drone plots.
  • The government's own terror adviser broke from official restraint to declare antisemitic violence 'the biggest national security emergency' Britain has faced in nearly a decade, a judgment rooted in the lived reality of a community losing confidence in its own safety.
  • The Home Secretary and Prime Minister moved swiftly but carefully — raising the threat level, pledging £25 million in security funding, and promising faster legislation — while resisting the constitutional weight of the word 'emergency' even as they treated the crisis as one.
  • Some attacks bear the fingerprints of foreign state involvement, particularly Iran, adding a geopolitical dimension that domestic policing and sentencing reform alone cannot resolve.
  • Jewish leaders, a Labour MP who grips her children's hands tighter on the way to synagogue, and opposition politicians across the spectrum are united in one verdict: security measures are necessary but not sufficient, and the root causes remain unaddressed.

On a Wednesday afternoon in Golders Green, two Jewish men — Shloime Rand, 34, and Moshe Shine, 76 — were stabbed in an attack police immediately classified as terrorism. A 45-year-old British national of Somali origin was arrested on suspicion of attempted murder. By Thursday evening, the UK had raised its national terrorism threat level from substantial to severe, a designation not used since February 2022.

The government's counterterrorism adviser, Jonathan Hall, told the BBC that antisemitic attacks now represent the biggest national security emergency Britain has faced in nearly a decade — grounding his assessment in a concrete reality: Jewish people across the country were increasingly convinced they could no longer live ordinary lives. Home Secretary Shabana Mahmood pushed back on the word 'emergency,' noting its constitutional implications, but acknowledged treating the issue as an absolute priority. Prime Minister Keir Starmer was direct: 'This has been a series of attacks on our Jewish community,' and he demanded responses that were swift and visible.

The stabbing was not an isolated event. In October 2025, a car ramming and stabbing outside a Manchester synagogue killed two people and left three seriously injured. In the months since, Jewish charity ambulances were set ablaze in a Golders Green car park, a synagogue in Finchley was targeted with a brick and suspected petrol bottles, an accelerant was thrown through a synagogue window in Kenton, and suspicious items appeared near the Israeli embassy amid claims of a planned drone attack. Some incidents bore signs of foreign state involvement, particularly Iran — though police found no such link to Wednesday's stabbing.

The government announced £25 million in additional funding for security around Jewish institutions and pledged legislation to counter hostile state threats, ban extremist organizations, bar hate preachers, and accelerate sentencing for antisemitic attacks. Chief Rabbi Sir Ephraim Mirvis was unsparing: 'If you are visibly Jewish, you're not safe.' Jewish communal bodies called themselves 'sickened' while insisting security measures alone were not the answer. Labour MP Sarah Sackman, who represents Golders Green and is Jewish herself, described gripping her children's hands tighter on the way to synagogue.

The deeper tension beneath the unified alarm was this: the government's own framing acknowledged that the problem extended beyond the security apparatus into public discourse and culture itself. Whether legislation, funding, and faster sentencing can meet a threat that is simultaneously organized, foreign, domestic, and cultural remains the question the announcements left open.

On a Wednesday afternoon in Golders Green, north London, two Jewish men were stabbed in what police immediately classified as a terrorist attack. Shloime Rand, 34, and Moshe Shine, 76, became the latest victims in a months-long escalation of violence targeting Britain's Jewish communities. A 45-year-old British national, who arrived in the UK from Somalia as a child, was arrested on suspicion of attempted murder. By Thursday evening, the government's response was stark: the national terrorism threat level jumped from "substantial" to "severe," a designation not seen since February 2022.

Jonathan Hall, the government's adviser on counterterrorism, went further than official channels. He told the BBC that antisemitic attacks now represent "the biggest national security emergency" Britain has faced in nearly a decade. His assessment centered on a stark reality: Jewish people across the country were increasingly convinced they could no longer live ordinary lives. The statement carried weight precisely because it came from someone whose job is to measure genuine threats to national security.

Home Secretary Shabana Mahmood pushed back on the language, though not the substance. She rejected the term "national emergency," noting it carries specific constitutional weight—the suspension of democratic safeguards. Yet she acknowledged treating the issue as an "absolute priority" and conceded that security measures alone could only address "the end of the problem." Prime Minister Keir Starmer, meeting with criminal justice agencies on Thursday, was blunt: "This has been a series of attacks on our Jewish community." He demanded responses that were "swift and visible."

The pattern preceding Wednesday's stabbing painted a portrait of sustained targeting. In October 2025, a car ramming and stabbing outside a Manchester synagogue killed two people and left three in serious condition. This year alone: four ambulances owned by a Jewish charity were set on fire in a Golders Green car park in March; a brick and bottles suspected of containing petrol were hurled at the Finchley Reform Synagogue in April; suspicious items appeared near the Israeli embassy with claims of a planned drone attack; an accelerant-filled bottle was thrown through a synagogue window in Kenton; and a suspected arson attack targeted a memorial wall in Golders Green honoring victims of Iranian state repression and the 2023 Hamas attack on Israel. Some of these incidents bore fingerprints of foreign state involvement, particularly Iran, though police found no such connection to Wednesday's stabbing.

The government announced £25 million in additional funding for police patrols and security enhancements around Jewish institutions—synagogues, schools, community centers. Starmer pledged faster legislation to combat what he called the "malign threat" posed by hostile states, with specific mention of Iran's Islamic Revolutionary Guard Corps. He committed to banning charities that promote antisemitism, barring hate preachers from entry, and accelerating sentencing for antisemitic attacks to create stronger deterrence.

Chief Rabbi Sir Ephraim Mirvis, representing the UK's largest Jewish community, delivered a stark assessment: "If you are visibly Jewish, you're not safe." He demanded "meaningful action" on root causes, not just security theater. The Board of Deputies and Jewish Leadership Council echoed this in a joint statement, calling themselves "sickened" by the attack while insisting that security measures, though essential, were "not the answer." Labour MP Sarah Sackman, who represents Finchley and Golders Green and is Jewish herself, described gripping her children's hands tighter on the way to synagogue, knowing she was not alone in that fear.

Opposition voices aligned with the terror adviser's assessment. Shadow Home Secretary Chris Philp called the frequency of attacks "shameful" and agreed this constituted a national emergency, declaring that "words are no longer enough." Nigel Farage urged "real action." Even the office of Israeli Prime Minister Benjamin Netanyahu weighed in, accusing the UK government of weakness in the face of repeated antisemitic violence.

Yet beneath the unified alarm lay a deeper tension. Mahmood's careful distinction between "emergency" and "absolute priority" reflected genuine constitutional caution. Starmer's acknowledgment that "far too many people in this country diminish" antisemitism suggested the government saw the problem as extending beyond security apparatus into the fabric of public discourse itself. The question hanging over the announcements was whether legislation, funding, and faster sentencing could address what appeared to be a multi-layered threat: organized foreign state actors, domestic extremists, and a broader cultural erosion of safety for visibly Jewish Britons.

When the terror adviser calls this a national security emergency and the Home Secretary says it isn't, who's actually right?

Model

They're both describing the same crisis in different languages. Hall is measuring the scale and nature of the threat—the pattern, the frequency, the fact that people are afraid to be visibly Jewish. Mahmood is protecting the constitutional meaning of "emergency," which has legal teeth. But she's not disagreeing that it's urgent.

Inventor

So the £25 million in security funding—is that enough?

Model

It's a response to the immediate problem: protecting buildings, increasing patrols. But listen to what the Jewish leaders said. They called security "not the answer." You can't fence in every synagogue in Britain. The real question is what's driving the attacks in the first place.

Inventor

The source mentions some attacks linked to Iran. How does that change things?

Model

It means this isn't just domestic hate crime. It's state actors using antisemitism as a weapon. That's why Starmer suddenly started talking about banning the Iranian Revolutionary Guard and fast-tracking legislation. When a foreign government is involved, the security response has to be different—diplomatic, intelligence-based, not just more police.

Inventor

But the Wednesday stabbing—police haven't linked that to Iran, right?

Model

Right. So you have both: foreign state involvement in some attacks, and what appears to be independent actors in others. That's actually more destabilizing because it means the threat is coming from multiple directions at once.

Inventor

What struck you most about the Jewish community's response?

Model

That they didn't just ask for protection. They asked for action on root causes. Sackman gripping her children's hands tighter—that's not a security problem you solve with funding. That's a cultural problem. And Starmer seemed to understand that when he said this is about "what sort of country do we want to live in."
