The United Kingdom has recorded the most substantial rise in antisemitic incidents among major countries outside of Israel, according to a new report by the J7 Large Communities’ Task Force Against Antisemitism. The study expresses alarm over "the deadly reality of antisemitism that Jewish communities worldwide confront at levels unprecedented since World War II."

The report, which analyzes data from nations representing the largest Jewish populations outside Israel—Argentina, Australia, Canada, France, Germany, the UK, and the US—indicates that antisemitic attitudes are becoming "more widespread."

This surge follows a period of heightened antisemitic attacks, including incidents at synagogues and an increase in online threats and abuse. The report notes that antisemitic incidents generally remain elevated compared to pre-October 7, 2023, levels, despite a decrease in four of the seven J7 countries last year following 2024 peaks. The Hamas attacks on Israel on October 7, 2023, which resulted in over 1,200 deaths, preceded a military response by Israel in Gaza that has led to an estimated 80,000 deaths.

Collectively, the seven countries documented over 91,000 antisemitic incidents in the past year. Germany reported 8,725 incidents, the US recorded 6,274, the UK had 3,700, Australia saw 1,654, France had 1,320, Canada reported 788, and Argentina registered 713.

Overall, reported antisemitic incidents across these nations have increased by 136 percent since 2022, with violent incidents rising by 97 percent. The UK, alongside Argentina and Germany, experienced an increase in incidents last year, with Britain's five percent rise being the steepest.

Marina Rosenberg of the US-based Anti-Defamation League, involved in the report, stated that social media has been a platform for radicalization and that artificial intelligence is now also a factor in the rise of antisemitic violence. The J7 Task Force warned that "Antisemitism in our seven countries is no longer a surge; it is our new normal," urging governments to implement proactive security funding, stronger laws, and enforcement of social media platform rules.

In the UK, specific incidents have fueled concern. In March, four Jewish charity ambulances were set on fire in Golders Green, north London. The firebombing caused gas canisters to explode, damaging a nearby synagogue. A former synagogue in Whitechapel, east London, was also the target of a suspected arson attack in May, prompting a counter-terrorism police investigation. Another incident in April involved attempted arson attacks at Finchley Reform Synagogue and outside the offices of a Persian media company.

British authorities have been urged to take more forceful action against extremists. The UK government has announced measures including a new law to act against state-backed groups and the proscription of Iran’s Islamic Revolutionary Guard Corps. Former Prime Minister Sir Keir Starmer had previously pledged a "zero tolerance" approach to antisemitism on university campuses and in the arts, with universities now expected to publish data on antisemitic incidents and the steps taken to address them. The Arts Council is to withdraw funding from those promoting antisemitism.

An independent audit of how antisemitism allegations are handled has also been ordered. Additionally, Jewish communities across England are to receive an extra £1 million for community safety and efforts to counter antisemitic narratives. A review into antisemitism in schools and colleges is also underway, following a doubling of school-related antisemitic incidents in 2025 compared to pre-2023 levels.
