The U.S. Embassy in Moscow warned Saturday of a “credible threat of a mass-casualty event” at the Tsaritsyno Museum Reserve, a palace and park complex in southern Moscow.

The embassy’s October 31 security alert urged people to avoid the site at 1 Dolskaya Street, stay away from crowds and remain alert. It also advised U.S. citizens to monitor local news, follow authorities’ instructions, keep their phones charged and carry identification. The embassy said the U.S. government was coordinating with Russian authorities.

Russia’s Federal Security Service said it had received information from U.S. partners about preparations for a terrorist attack in Moscow and was taking appropriate measures, according to Russian state media cited by news organizations.

Global Affairs Canada repeated the U.S. warning and continued to advise against all travel to Russia, citing the war in Ukraine and the risk of terrorism. It urged Canadians in Russia to consider leaving by commercial means or maintain a low profile if they remain.

The U.S. alert did not identify who might be responsible, describe a suspected plot or specify possible targets within the reserve. It also did not say whether the site had closed or whether arrests had been made. No attack or injuries were immediately reported.
