Update: Russia’s Federal Security Service confirmed that it had received a U.S. warning about a planned terrorist attack in Moscow. “Appropriate action is being taken,” the agency said. Security guards told a reporter from the outlet Ostorozhno Media that the Tsaritsyno Museum-Reserve had been closed “for technical reasons.”
The U.S. Embassy in Moscow issued a security alert saying it had learned of a threat to the Tsaritsyno Museum-Reserve:
The U.S. Embassy in Moscow is aware of a credible threat of a mass casualty event TODAY October 31, at the Tsaritsyno Museum Reserve in Moscow at Dolskaya Ulitsa 1, Moscow, Russia 11569. The U.S. government is coordinating with appropriate Russian authorities on a response.
The alert lists precautions the embassy recommends for U.S. citizens:
- Avoid the Tsaritsyno Museum Reserve location TODAY, October 31, 2026. Avoid the area, stay alert, and avoid crowds.
- Be aware of your surroundings.
- Review your personal security plan.
- Keep your cellphone charged in case of emergency.
- Carry proper identification.
- Monitor local media for any further information
- Enroll in the Smart Traveler Enrollment Program (STEP ) to receive health and security updates.
Moscow city officials and Russian federal authorities have not commented on the alert.
A museum representative told the Telegram channel Mash that staff had no information about a threat. Tsaritsyno continues to operate as usual.
The U.S. Embassy issued a similar warning in early March 2024 — shortly before the terrorist attack at Crocus City Hall outside Moscow.
