instability russians can feel it. the rebel wagner fighters may not have made it to moscow, but people here were watching nervously and waiting. i m a mother with three children, anna tells me. of course i m terrified by what has happened. we were scared these events would spread to moscow, nastya says. there s nothing ordinary citizens can do to influence the situation. it s decided above our heads. many russians tell me that they don t believe they have the power to change what is happening in their country, to make their voices heard, to turn things around. as steve rosenberg reports, the past 48 hours call into question just how firm vladimir putin s grip on russia actually is.
