Antisemitic crimes rise nearly 20% in Britain after Iran war

By the Editorial Team · Thursday, August 6, 2026

Antisemitic incidents in Britain surged by nearly 20% in the first half of 2026, with 1,926 reported cases including violent attacks linked to pro-Iranian terrorist groups. The rise has prompted the UK government to designate associated organizations as terrorist entities and intensified calls from officials to address antisemitism as a national crisis.

Antisemitic incidents in Britain have risen sharply in the first half of 2026, according to data from the Community Security Trust (CST). Between January and June, 1,926 antisemitic incidents were reported, marking an increase of nearly 20% compared to the 1,598 recorded during the same period last year. This figure represents the second-highest six-month total on record, surpassed only by the 2,019 incidents logged in the first half of 2024.

The rise in antisemitism comes amid heightened tensions linked to the war involving the United States, Israel, and Iran. In early 2026, several attacks targeted Jewish sites in London, including a series of arson attempts on four Jewish community ambulances. A notable incident occurred on April 29 in Golders Green, where two Jewish men were seriously injured in a double stabbing incident classified as a terrorist attack. Following this event, the CST recorded 71 antisemitic acts over the ensuing three days, some of which openly celebrated the violence and propagated antisemitic conspiracy theories.

The Islamic Movement of Companions of the Right, a terrorist organization reportedly connected to pro-Iranian networks, has claimed responsibility for several attacks, including the firebombing of the Jewish ambulances. In response, the UK government designated both this group and Iran’s Islamic Revolutionary Guard Corps as terrorist entities under existing counterterrorism laws in July.

Sarah Jones, the policing and crime minister, described the statistics as “appalling,” highlighting the sense of fear among Jewish communities. Mark Gardner, chief executive of the CST, emphasized the significance of the threat, warning that it stems not only from foreign state actors like Iran but also from extremist elements across the Islamist spectrum, as well as far-right and far-left groups within the UK.

Political figures have also expressed concern. Chris Philp, the shadow home secretary, labeled antisemitism in Britain as “a national emergency,” underscoring the urgency of addressing the issue at all levels of government and society.
