Germany, following the United States, warned its citizens of a "security threat" in Tsaritsyno. The German Embassy in Moscow yesterday advised citizens of the country to avoid Tsaritsyno Park "due to specific indications of an ongoing security threat", Der Spiegel writes. "Please maintain vigilance in general and also avoid crowds and public places," reads the email sent to German citizens in Russia. Yesterday, the US Embassy in Moscow warned of a "threat of an incident with a large number of casualties" in Tsaritsyno on October 31. The FSB confirmed that they had received information about the preparation of a terrorist attack in Moscow, and the museum was closed. Today the museum-reserve operates as usual, writes the parliamentary newspaper.
