According to a new report, dozens of antisemitic incidents were reported across the UK after two Jewish men, aged 76 and 34, were stabbed in the Golders Green terror attack on April 29.

The Community Security Trust recorded 71 incidents in the following three days, including 16 that directly referred to the stabbing, while the day of the attack saw the highest daily total of the first half of 2026.

Antisemitic incidents across the UK rose by 21 per cent in the first half of 2026, according to the Community Security Trust (CST) latest report.

CST is an organisation that provides security support to the British Jewish community,

The report recorded 1,926 cases which is the second-highest total ever recorded for this period. Physical attacks rose sharply, with 135 recorded antisemitic assaults, an 82% increase year-over-year.  By comparison, 2025 saw 1,598 incidents recorded in the first half of 2025.

In the six months leading up to 7 October 2023, CST recorded a monthly average of 161 antisemitic incidents per month. In the first six months of 2026, this monthly average was 321 incidents, a 99% increase from that earlier period. Prior to October 2023, CST had only ever recorded monthly incident totals exceeding 200 on five occasions, and over 300 twice, each correlating with past periods when Israel was at war. In the first half of 2026, CST logged over 200 instances of anti-Jewish hate in every month, and over 300 in March, April, May and June.

CST recorded 21 antisemitic incidents on the day of the Golders Green stabbing attack against two Jewish men, aged 76 and 34, on April 29, the joint-fourth highest daily total in the first half of the year; 24 antisemitic incidents on the day after the attack, the joint-third highest daily total between January and June; and 26 antisemitic incidents on the day following that, the highest daily total of the period. Of the 71 cases of antiJewish hate recorded across these three days, 16 (23%) were explicitly linked to the stabbing. Four involved face-to-face abuse directed at Jewish people in public – including at those who gathered in Golders Green in solidarity with the Jewish community in the hours following the attack – and 12 took place on social media or via email.

The Golders Green knife attack was the sole incident severe enough to be categorised as Extreme Violence in the first half of 2026, meaning it involved a threat to life of Grievous Bodily harm (GBH). This is a fall from the three such incidents reported between January and June 2025.

Incidents in schools jumped 59% to 178, while synagogue-related incidents surged by 31%.

CST recorded 135 incidents as Assault in the first six months of 2026, an increase of 82% from 74 incidents of this type reported in the first half of 2025 and the highest ever six-monthly total in this category. Taken together with the single case of Extreme Violence, physical attacks on Jewish people constitute 7% of the six-monthly total, compared to 4% in the corresponding period in 2025. It is notable that of these 136 acts of physical violence, 93 (69%) occurred over the 77 days between the arson attack on Finchley Reform Synagogue on 15 April and 30 June: 43% of the period covered in this report. This may indicate that not only did the overall volume of antisemitism increase following this incident, but the general severity of the antisemitism did too.

CST Chief Executive Mark Gardner commented : “These attacks are directed against British Jews but they are also attacks on Britain and our society. They should concern everyone who cares about Britain and the threats against it, whether state-directed from Iran, or internally driven by Islamist, far-right, far-left, or other ideological extremes.”

Separate data released last week revealed that antisemitism is at heightened levels globally.

The government’s independent adviser on antisemitism, Lord John Mann, said these new CST figures, “demonstrate that anti-Jewish racism in the UK remains at all all-time high and continues to pose a significant threat to our democracy”.

He added that he is especially concerned “to see the nature of antisemitism in the UK becoming increasingly violent”.
