"The illegal activity of the extremist community was aimed at discrediting government bodies and their policies, destabilizing the situation in regions, igniting protest sentiments among the population and shaping public opinion about the need for a violent change of power, organizing and holding protest actions that escalate into riots," the statement read.
The committee said the leaders and members of the community had "systematically" held unauthorized public events across Russia from 2014 to 2021, during which they called for extremist and terrorist activities, breached law and order and jeopardized public safety.
Navalny, Volkov and Zhdanov are accused of creating and managing an extremist community, while Sobol and several other supporters of the opposition activist are accused of participating in it.
