In Moscow, security forces and special equipment were deployed to the Tsaritsyno Museum reserve due to a threat of a terrorist attack. It was reported that about 80 law enforcement officers and several dozens of equipment arrived at the museum reserve area. Among them are about 50 riot police officers, employees of the Russian guard, dogs of the Ministry of the Interior with dogs, saboteurs with a mine clearing robot, firefighters and police. All entrances to the museum reserve are blocked. Traffic police officers check cars near the checkpoints. The Tsaritsino area has been closed for about five hours. Earlier, the US Embassy in Russia warned of a "credible threat of an event that could cause mass casualties" on the territory of the museum reserve. The FSB reported that it received information from the American side about the preparation of a terrorist attack in Moscow and is carrying out appropriate work.
