Overview
- The Community Security Trust recorded 1,926 antisemitic incidents in Jan–Jun 2026, a 21% rise on the same period in 2025 and the second-highest six-month total on record.
- The rise included violent attacks treated as terrorism and coordinated arson, including the April 29 Golders Green stabbing that sparked a three-day surge and the torching of volunteer Hatzola ambulances in March.
- Authorities have linked several incidents to a group calling itself Harakat Ashab al-Yamin al-Islamia (HAYI) and to suspected Iran-linked networks, while Iran denies involvement.
- U.S. prosecutors have charged Mohammad Al Saadi with orchestrating nearly 20 attacks after his arrest in Turkey and extradition to the United States, and the UK sanctioned HAYI in July.
- The surge is concentrated in Greater London and Greater Manchester, has raised fear across Jewish communities, and has prompted calls for prevention-focused measures beyond short-term security upgrades.
