Russian opposition leaders argued on Sunday over the turnout and success of the latest rally defying President Vladimir Putin, after tens of thousands marched through central Moscow. The rally on Saturday, called the March of Millions, featured slogans mocking Putin and calling for the release of jailed punk band Pussy Riot. Police put numbers at around 14,000, down from 18,000 at a previous rally in June. But rally organisers gave varying estimates of up to 150,000. RFI talked to Yuri Dzhibladze, the founder of a human rights watchdog group who attended the demonstration in Moscow.
