L'arresto di una dissidente che manifesta per i diritti costituzionali di fronte al Cremlino

Police officers detain an opposition activist during a banned anti-Kremlin protest in St. Petersburg, Russia, Sunday, July 31, 2011. Opposition groups have been calling rallies on the 31st day of each month to honor the 31st article of the Russian Constitution, which guarantees the right of assembly. Most of the rallies have been banned or dispersed by police as unsanctioned. (AP Photo/Dmitry Lovetsky)
