"U.S. Embassy Urges Americans to Avoid Moscow Crowds Amid Imminent Terror Threat"

The U.S. Embassy in Moscow has warned American citizens to avoid large gatherings in the city due to heightened fears of a terrorist attack, without specifying the source of the threat. This comes after Russia's FSB security service claimed to have thwarted a planned attack by an Afghan offshoot of the Islamic State on a synagogue near Moscow. Tensions between the U.S. and Russia have escalated, with the U.S. criticizing Russia's designation of American educational and exchange organizations as "undesirable," leading to a ban on their activities in the country.
