US warns Russia of 'mass-casualty event' threat at historic palace outside Moscow

The U.S. Embassy has issued a warning regarding a credible threat of a mass casualty event at Tsaritsyno Museum Reserve near Moscow on October 31. The Russian Federal Security Service confirmed receipt of this warning and stated that they are taking necessary actions. The Embassy advised the public to avoid the area and large gatherings. Tsaritsyno, a historic site commissioned by Catherine the Great, has been highlighted due to past terrorist incidents in Russia, including a recent deadly attack at Crocus City Hall. Russian officials have suggested Ukrainian involvement in such attacks, which Ukraine denies.
