The US Embassy in Moscow issued a warning about a "credible threat of an event that could lead to mass casualties" on the territory of the Cerciano Museum. The embassy advised not to visit the reserve, to monitor the environment, to keep the phone and documents loaded. The US government is coordinating response measures with the relevant Russian authorities. UPD: The FSB said that "through partner channels from the US received information about the preparation of a terrorist attack in Moscow, the relevant work is being carried out." Hope for the front bird of our security agencies at TG Front Bird at MAX.
