People attend a sanctioned rally on a bridge near Bolotnaya square to protest against violations at the parliamentary elections in Moscow December 10, 2011. Tens of thousands of protesters took to the streets of cities across Russia on Saturday to demand an end to Vladimir Putin's rule and complain about alleged election fraud in the biggest show of defiance since he took power more than a decade ago. The banner reads "Swindlers and thieves, give back the elections". REUTERS/Denis Sinyakov (RUSSIA - Tags: POLITICS ELECTIONS CIVIL UNREST)
