Thousands protested in central Moscow on Sunday over a proposed increase to the retirement age and the crowd chanted slogans critical of President Vladimir Putin whose approval ratings have been dented by the bill.
The rally organized by the opposition Libertarian Party chanted "Putin is a thief" and "away with the tsar," slogans common at anti-Putin and anti-government protests.
The retirement age proposal is politically sensitive for Putin, who was re-elected in March, because it has prompted a series of protests across Russia since it was announced on June 14, the day Russia played the first match of its soccer World Cup.
