On 22 January 2021, the U.S. Embassy in Moscow issued a Demonstration Alert, which reads in part as follows: “Event: Media sources indicate that on Saturday, January 23, demonstrations are being planned throughout Russia in support of an opposition activist. These demonstrations are likely to be unauthorized. Given the likely substantial police presence and possible dispersal of demonstrators into other areas of the cities, U.S. citizens should avoid these demonstrations and any demonstration-related activities.”
The full text of the alert – which includes details of protests in major cities – can be read here.
