The UK government raised the country’s official threat level from terrorism from substantial to severe on Thursday, after two Jewish men were stabbed in north London the day before in what police are calling an act of terrorism.
Severe is the second-highest rung on a five-point scale and means intelligence agencies consider an attack highly likely in the next six months.
Officials in Westminster said that the country is facing an antisemitism emergency and pledged to increase security for Jewish communities after a string of attacks that have sparked fear and anger among Jews.
Prime Minister Keir Starmer said that his government “will do everything in our power to stamp this hatred out” after two Jewish men, ages 34 and 76, were seriously injured in a stabbing in Golders Green, an area in north London that is an epicentre of Britain’s Jewish community.
Both men are in a stable condition.
But some in the community turned their anger on the government, which they say is failing to tackle antisemitism.
Starmer was heckled by about 100 protesters holdings signs saying “Keir Starmer, Jew harmer” when he visited Golders Green on Thursday.
The prime minister said in response that “I absolutely understand the high levels of anxiety and concern that there are.”
“Antisemitism is an old, old hatred. History shows that the roots are deep, and if you turn away, it grows back,” he said during a televised statement at Downing Street.
“Yet far too many people in this country diminish it.”
Police have arrested a 45-year-old man on suspicion of attempted murder and labelled the stabbing attack as an act of terrorism.
Detectives are working to determine a motive and whether there is any link to Iranian proxies.
The suspect, whose name hasn’t been released, had “a history of serious violence and mental health issues” and may have been involved in an “altercation” in another area of London hours before the Golders Green attack, police said.
In 2020, he was referred to the government’s Prevent programme, which tries to steer individuals away from extremism.
The police force said that his file was closed later the same year and didn’t disclose the reason for the referral.
Stabbings follows arson attacks
Britain’s Jewish community, which numbers about 300,000, has faced growing attacks online and in the streets.
The number of antisemitic incidents reported across the UK has soared since the attack by Hamas-led militants on southern Israel on 7 October 2023 and the subsequent war in Gaza, according to the Community Security Trust charity.
Last October, an attacker drove his car into people gathered outside a Manchester synagogue on Yom Kippur and fatally stabbed one person.
Another person died during the attack after being inadvertently shot by police.
Since the start of the Iran war on 28 February, there have been a string of arson attacks on synagogues and other Jewish sites in London as well as on opponents of the Iranian government.
Police say that 28 people have been arrested over those attacks, which did not cause any injuries.
A handful have been charged and one teenager has been convicted after pleading guilty.
Police investigating possible links to Iran proxies
Several arson attacks have been claimed online in the name of Harakat Ashab al-Yamin al-Islamia.
Israel’s government has described the group, whose name means the Islamic Movement of the Companions of the Right, as a recently founded group with suspected links to “an Iranian proxy” that has also claimed responsibility for attacks on synagogues in Belgium and the Netherlands.
An online post under the same name also claimed responsibility for Wednesday’s stabbing.
Home Secretary Shabana Mahmood said that authorities were investigating whether that claim is credible or “opportunistic.”
Security experts have warned that the name may be a flag of convenience rather than a coherent group and its claims should be treated with caution.
The UK has accused Iran of using criminal proxies to conduct attacks on European soil targeting Iranian opposition media outlets and the Jewish community.
Britain’s MI5 domestic intelligence service says that more than 20 “potentially lethal” Iran-backed plots were disrupted in the year ending in October.
