Antisemitic Incidents in UK Surged After Lethal Attack at Manchester Synagogue on Yom Kippur

Antisemitic incidents in the United Kingdom spiked to their highest levels last year following the deadly attack at Heaton Park Synagogue in Manchester on Yom Kippur, the holiest day in Judaism, according to newly released data.

The Community Security Trust (CST), a nonprofit charity that advises Britain’s Jewish community on security matters, revealed in an annual report published on Tuesday that Oct. 2, the day of the car-ramming and stabbing attack that left two Jewish worshippers dead and three seriously wounded, saw 40 recorded antisemitic incidents. Another 40 such outrages occurred the next day.

These were the two highest daily totals for antisemitic incidents in 2025. More than half of the incidents included direct responses to the Manchester violence, with some celebrating what transpired.

Melvin Cravitz and Adrian Daulby, the Jews killed in the attack by Jihad Al-Shamie on Oct. 2, are the first victims of a lethal antisemitic terrorist attack in the UK since CST began tracking incidents in 1984.

In its latest report, the CST identified the surge in incidents as a perennial pattern following terrorist attacks targeting Jews.

Overall, CST recorded 3,700 antisemitic incidents in the UK in 2025, the second-highest total ever in a single calendar year and an increase of 4 percent from the 3,556 in 2024.

This is the first report in which more than 200 incidents occurred in every month. The year averaged 308 antisemitic incidents each month — an exact doubling of the 154 monthly average in the year before the Hamas-led Oct. 7, 2023, massacre across southern Israel.

“The tensions that exist in our society have not abated and are both deeper and more long-standing than anything we have experienced in modern times,” said Chief Constable Mark Hobrough, the UK’s national head for policing hate crimes, who called the figures “unacceptably high.”

Antisemitic incidents had fallen from the record high of 4,298 in 2023, which analysts say was fueled by Hamas’s Oct. 7 attack — the biggest single-day massacre of Jews since the Holocaust — when Palestinian terrorists slaughtered 1,200 people, kidnapped 251 hostages, and engaged in sadistic acts of brutal barbarism that one Israeli NGO described in a 2025 report as the “tactical use of sexual violence.”

According to CST’s report, “the enduringly high incident levels and type of content reported since the initial Hamas attack on Oct. 7, 2023, partly reflect the unprecedented length of the subsequent war, its geographical reach from Gaza to Lebanon and Iran, and its consequent continued foregrounding in media, politics and public debate. Anti-Israel protests have persisted, as did vigils for the hostages held in Hamas captivity and marches against antisemitism.”

Similar to the data observed in its latest report of increased antisemitic incidents following the Manchester synagogue attack on Yom Kippur, CST’s prior research also affirmed the trend in noting that 416 of 2023’s incidents took place in the week after the Oct. 7 massacre.

A surge of UK incidents also occurred on the day of and in the two days following the antisemitic terrorist attack at Bondi Beach in Sydney, Australia which left 15 dead. The alleged perpetrators are a father and son team. The father, Sajid Akram, has reportedly praised Islamic State and a top Al Qaeda propagandist.

“Two years of intense anti-Jewish hatred culminated in a jihadi terror attack at a synagogue on the holiest day of the Jewish calendar,” CST chief executive Mark Gardner said in a statement. “The terror attack then triggered even more antisemitism, showing the depths of extremism faced by Jews and all our British society.”

Gardner said the increase in violence and terrorism “makes CST even more determined to keep protecting our community, giving it strength and dignity so it can lead the life of its choice.”

Home Secretary Shabana Mahmood said in response to the report that the government was “providing record funding for security at synagogues, Jewish schools, and community centers.” She vowed, “I will go further to strengthen police powers so they can crack down on intimidating protests.”

Anti-Israel sentiment fueled antisemitism, according to the CST’s data, which showed that 1,977 incidents involved references to Israel, Palestine, the Hamas attack, or the ensuing war in Gaza. “This was true of 52 percent of the incidents reported in 2024, 43 percent of those in 2023, and 15 percent of those in 2022: a year unaffected by a significant trigger event in the region,” CST noted.

According to the report, 170 incidents in 2025 involved an assault, which represents a drop of 16 percent from 2024’s 202.

Geographically, the CST identified the majority of incidents (61 percent) occurring in Greater London (1,844) and Greater Manchester (425) since “these hubs of Jewish life are where the majority of the UK’s Jewish community resides and remain the main targets of anti-Jewish prejudice.” Other hot spots for antisemitism in the UK included West Yorkshire (131), Hertfordshire (126), Scotland (101), Sussex (68), Essex (67), and West Midlands (67).

“In all walks of life, Jewish people have been attacked, targeted, ostracized and excluded,” said John Mann, who serves in the House of Lords and as the country’s independent adviser on antisemitism. “Anti-Jewish racism is present in every sector and every corner of society.”

A further trend that CST identified was the evolving nature of antisemitism in the UK, noting that far right and far left narratives have begun to blend together in an expression of what political scientists have described as the “horseshoe theory” wherein extremists from both sides of the ideological spectrum come to unite around recognizing their common enemy.

“The far-right discourses pervading Israel-related antisemitism showcase the mechanism of contemporary anti-Jewish hate, wherein traditional doctrines of extreme left-wing and extreme right-wing antisemitism overlap in their centralizing demonization of Israel, Zionism and, to varying degrees of unambiguity, Jews,” the report stated.
