Police have detained about 100 people on Manezhnaya Square in central Moscow for violating public order, the Moscow city police department told Interfax on Tuesday.
"About 1,500 people gathered on Manezhnaya Square on Tuesday evening to hold an unsanctioned event. There were also groups of people near the square expressing their disagreement with those who had gathered there," it said.
"Police repeatedly called on the participants not to violate public order," it said.
About 100 people were eventually detained and taken to police stations "to be held liable in line with the law."
An Interfax correspondent reported earlier from Manezhnaya Square that police had started ousting the demonstrators from the venue of the gathering.
Using a loudspeaker installed on a vehicle, police had called on the demonstrators for about 10 minutes "not to fall for provocation," "be calm and reasonable," and disperse.
After that, police formed several lines and started gradually ousting the activists and journalists from Manezhnaya Square toward the Ploshchad Revolutsii metro station, detaining those who offered resistance.
Police also blocked the entrance to Red Square from Manezhnaya Square.
Metal fences have been put to block the entrance to Red Square. At the same time, the exit from Red Square at this point is free.
The entrances to Alexander's Garden and to Manezhnaya Square have also been closed.
Earlier on Tuesday, Moscow's Zamoskvoretsky District Court had given Alexei Navalny a suspended prison term of 3.5 years, while his brother Oleg Navalny had received a real jail time of 3.5 years in a case dealing with embezzlement from the French cosmetic firm Yves Rocher.
