The United States has warned Russian authorities of a potential terror threat, pointing to an imminent "mass casualty event" targeting a landmark museum estate in Moscow.
In an urgent security alert issued on Saturday, the US Embassy named the Tsaritsyno Museum Reserve as the specific target of the planned attack, advising all American nationals in the Russian capital to avoid the site and stay clear of large crowds. The museum was established in 1775 and after a restoration in the 1980s has remained a popular tourist destination in the city.
