The United States Embassy in Moscow warned Russian authorities of a credible threat of a multiple-casualty terrorist attack targeting the Tsaritsyno Museum-Reserve in the southern part of the Russian capital, CNN Portugal reported. The diplomatic mission urged American citizens to avoid the cultural institution, where a concert was scheduled for the evening.
Tsaritsyno Museum-Reserve Threat Details
The security alert issued by the U.S. embassy specified that the potential attack targeted the museum grounds located at Dolskaya Street, 1, in Moscow, according to Metrópoles. Spanning over 405 hectares, the Tsaritsyno Museum-Reserve combines neo-Gothic palaces with extensive forests, bridges, and lakes, making it a popular destination for local residents. Because of the security warning, local law enforcement temporarily closed the park, as reported by Tribuna do Sertão via Sputnik.
Russian Security Agency Confirms Receiving Intelligence from American Authorities
The Russian Federal Security Service (FSB) confirmed that it received the intelligence from U.S. authorities through established cooperation channels, according to Metrópoles. The security agency stated that necessary preventive measures were being taken in response to the warning. Meanwhile, the U.S. embassy noted that the American government was actively coordinating a response with competent Russian authorities.

Precedent from the Crocus City Hall Attack
The embassy issued a similar intelligence warning in 2024, just two weeks before a major terrorist attack at the Crocus City Hall concert venue in Moscow. During that prior incident, armed attackers from the Islamic State (ISIS) opened fire on the audience attending a concert by the Picnic band and set the building on fire, resulting in 144 deaths according to Metrópoles figures (while CNN Portugal notes 151 fatalities). The Islamic State’s Khorasan branch (ISIS-K) claimed responsibility for the 2024 massacre.
