Russia’s Federal Security Service (FSB) ​said it had received information from ‌the United States through established partner channels about preparations for a terrorist attack ​in Moscow and was taking ​appropriate measures.

The U.S. Embassy in Moscow ⁠said separately it was “aware of ​a credible threat of a mass casualty ​event” on Saturday at Moscow’s Tsaritsyno Museum Reserve and that the U.S. government was ​coordinating with Russian authorities.

The Tsaritsyno ​Museum Reserve, a palace museum and park complex ‌south ⁠of Moscow, was temporarily closed on Saturday and access to the park is currently restricted, the RIA news agency ​reported, ​citing Russian ⁠law enforcement agencies.

Russian tabloid Baza reported that the venue was evacuated toward the end of an organ concert, which was cut short with about ten minutes left in the program. A separate concert dedicated to the folk traditions of the North Caucasus region was subsequently canceled, the outlet reported.

In March 2024, the U.S. Embassy warned ​that extremists had imminent plans ​for ⁠an attack in Moscow. Days later, gunmen attacked the Crocus City Hall ⁠concert ​venue outside Moscow, killing ​more than 140 people.
