On October 31, 2026, the U.S. Embassy in Moscow issued a security alert warning of a credible threat of a mass casualty event at the Tsaritsyno Museum Reserve in Moscow. The museum, an imperial palace and park complex attracting over two million visitors annually, was temporarily closed by Russian authorities as a precautionary measure. Russia’s Federal Security Service (FSB) confirmed receiving information from the U.S. about potential terrorist activities through established channels and reported taking appropriate security measures. Both U.S. and Canadian embassies advised against travel to the area due to the threat.
