The US embassy in Moscow said people should avoid concerts and crowds and be aware of their surroundings.
The US embassy in Russia on Friday warned that extremists had imminent plans for an attack in Moscow, hours after Russian security services said they had foiled a planned shooting at a synagogue by a cell from the Afghan arm of Islamic State.
Americans in Moscow have been told to avoid concerts and crowded areas amid warnings of an imminent terror attack.“The embassy is monitoring reports that extremists have imminent plans to target large gatherings in Moscow, to include concerts, and US citizens should be advised to avoid large gatherings over the next 48 hours,” the embassy said on its website.
The FSB said an Islamic State cell was operating in Russia’s Kaluga region as part of the Afghan arm of the group, which is known as ISIS-Khorasan and seeks a caliphate across Afghanistan, Pakistan, Turkmenistan, Tajikistan, Uzbekistan and Iran.
