What The Embassy Said
"The U.S. Embassy in London notes recent attacks and threats targeting Jewish and American institutions in the United Kingdom and Europe. U.S. citizens, particularly those visiting institutions serving Jewish or American interests, should remain alert and exercise increased caution."
Advice For Travelers And Residents
The embassy recommended that Americans:
Britain's Prime Minister Keir Starmer speaks during a visit to Kenton United Synagogue in the Kenton district of London, Britain, on April 23, 2026. The synagogue was recently the target of an arson attack.
- Remain vigilant in tourist and expatriate neighborhoods and at houses of worship.
- Review and update personal security plans before travel and while abroad.
- Monitor local media and follow guidance from local authorities and community leaders.
- Enroll in the State Department's Safe Traveler Enrollment Program (STEP) to receive official travel and security updates.
Recent Incidents Cited
The advisory followed several incidents described by authorities as antisemitic, including:
Police officers patrol near Kenton United Synagogue in Harrow, a suburb of London, on April 19, 2026.
- An arson attack on four ambulances linked to a Jewish charity in London on March 23.
- An attack at Kenton United Synagogue in London on April 18.
- An explosion at a Jewish school in Amsterdam in March that investigators treated as a targeted attack; no injuries were reported, though the building was damaged.
Investigations And Government Response
U.K. authorities are investigating reports that organised groups—described by some outlets as "thugs for hire" and possibly backed by Iranian interests—may be involved in the London incidents. Prime Minister Keir Starmer told the Jewish Chronicle that the government plans to introduce legislation to proscribe malign state actors and take other necessary measures.
The embassy advisory underscores growing concern among officials and communities about targeted threats and the need for heightened vigilance and institutional precautions across the region.
