US Embassy in Moscow warns of possible terrorist attack at Tsaritsyno museum-reserve

The US Embassy in the Russian capital, Moscow, announced on Saturday that it had warned the Russian side about a possible attack at the Tsaritsyno museum-reserve. Russia's Federal Security Service (FSB), the country's state security agency, confirmed that it had received a warning from the United States about preparations for a terrorist act. The report matters because it concerns possible mass casualties in Moscow, and it shows that security services of the two countries are exchanging information about threats.

What the embassy said

The US Embassy stated that it had information about credible threats of a mass-casualty situation in Moscow, at the Tsaritsyno museum-reserve. The embassy's statement, as far as the available information goes, gives no further details about the nature of the possible attack, who might be behind it, or when it could happen.

FSB confirmation

The Russian news agency TASS, citing the FSB, reported that the Russian security service had received information from the US through partnership channels about the preparation of a terrorist act in Moscow. Both sides therefore confirm that the warning was passed on and received.

The source does not say what measures the security authorities have taken since receiving the warning.
