More than 80 people were arrested during protests in St. Petersburg against planned pension reforms on Sunday.
Opponents of a Russian government move to increase the age for collecting state retirement pensions have held protests throughout the country on Sunday and scores of arrests were reported.
The protests were called by Alexei Navalny, the anti-corruption activist who is President Vladimir Putin’s most prominent foe.
Opposition to the proposal spans the political spectrum.
The plan calls for the pension age to be raised five years – to 65 for men and 60 for women.
