The US Embassy warned of a possible threat to Tsaritsyno in Moscow. Response Measures Coordinated with Russian Authorities The US Embassy reported a "credible threat" of a mass casualty incident in Tsaritsyno, Moscow on October 31. Americans have been urged not to visit the park, and Washington is coordinating the response with Russian authorities. Details of the alleged threat have not been disclosed. The FSB confirmed receiving information from the US about the preparation of a terrorist attack in Moscow through partner channels. The department said that appropriate work is being done. Moscow and Washington continue to maintain contacts through the intelligence services, despite political differences. As Vladimir Putin emphasized on September 1, "there are always contacts, there always have been, even in the most difficult times." After the October conversation between the presidents, Yuri Ushkov also confirmed that the parties are satisfied with the existing communication channels. In August, CIA Director John Ratcliffe visited Moscow and met with SVR head Sergei Naryshkin and, according to the New York Times, with FSB Director Alexander Bortnikov. The latter previously noted that the cooperation between the Russian and American intelligence services in the fight against terrorism continues partially.
