"U.S. Embassy Issues Terror Warning for Moscow Amid Imminent Attack Threat"

The U.S. Embassy in Moscow issued a security alert warning of "imminent plans" by "extremists" to target public gatherings, including concerts, in the Russian capital over the next two days, advising American citizens to avoid large gatherings. The embassy's statement came after Russia's Federal Security Service reported killing Islamic State militants planning a "terrorist attack" on a Moscow synagogue, but it was unclear if the embassy's alert was related to that incident.
