"The police confirm that about 600 people were detained during rallies in Moscow. The Ministry of Internal Affairs estimated the number of participants as of 1,500," the report said.
Among the detainees, there is an unregistered candidate for the Moscow City Duma, Lyubov Sobol, as well as journalists and foreigners.
The Ministry claimed that the Russian government cannot provide the integrity of democratic expression of will, fearing political competitiveness.
"Barbaric beating of its own citizens, multiple arrests and detentions, the use of artificial and discriminative pre-election filters supposed to let only the favorable candidates run during the election shows Russian government's failure to provide the integrity of democratic expression of will; it shows its fear of the real political competitiveness", reads the statement.
