"U.S. Embassy Issues Warning of Imminent Terrorist Attack in Moscow"

The U.S. embassy in Russia issued a warning of an imminent attack by "extremists" in Moscow, advising citizens to avoid large gatherings and concerts. This comes after Russian security services announced the foiling of a planned shooting at a synagogue by a cell from the Afghan arm of Islamic State. The embassy did not provide further details about the threat, while the Russian Federal Security Service stated that the Islamic State cell was preparing to attack the synagogue using firearms and was subsequently neutralized by Russian special forces.
