The U.S. Embassy in Moscow issued a security alert on Saturday, October 31, warning of a credible threat of a mass casualty event at the Tsaritsyno Museum Reserve in Moscow. The alert identified the museum’s location at Dolskaya Ulitsa 1, Moscow, Russia 11569, and urged people to avoid the area and remain alert.
The U.S. government stated it is coordinating with Russian authorities in response to the threat. The Russian FSB security agency confirmed it had received information about potential preparations for a terrorist attack from U.S. intelligence through partner channels, adding that ‘appropriate measures are being taken.’
The Tsaritsyno Museum, a popular tourist attraction founded in 1775 as a summer residence for Catherine the Great, attracts over two million visitors annually. The surrounding grounds are also frequented by locals for recreation. The U.S. Embassy advised those in Moscow to keep devices charged, stay aware of surroundings, and review personal security plans.
Background and Context
The warning comes amid escalating tensions between Russia and Ukraine. On Friday, October 30, Ukraine conducted a strike on an oil refinery in southern Russia, ending a two-week pause in energy infrastructure attacks. The previous day, Russian drone and missile strikes in Ukraine killed at least 27 civilians, according to reports.
Ukrainian President Volodymyr Zelensky has indicated openness to peace talks, suggesting negotiations could begin as early as November 10 in Abu Dhabi, led by a U.S. team. Zelensky stated Kyiv is prepared to discuss any topics, including sensitive issues, to advance negotiations. He also urged international actors to recognize Russia as the aggressor in the conflict.
The U.S. Embassy’s alert did not specify who may be responsible for the threatened attack. Russian authorities have not provided further details on the nature of the threat or any preventive actions taken.
Officials continue to monitor the situation as a developing story.
