An injured man lies on the ground as Turkish protesters clash with riot police near the former Ottoman palace, Dolmabahce, where Turkey's Prime Minister Recep Tayyip Erdogan maintains an office in Istanbul, Turkey, late Saturday, June 1, 2013. Turkish police retreated from a main Istanbul square Saturday, removing barricades and allowing in thousands of protesters in a move to calm tensions after furious anti-government protests turned the city center into a battlefield. A second day of national protests over a violent police raid of an anti-development sit-in in Taksim square has revealed the depths of anger against Prime Minister Recep Tayyip Erdogan, who many Turks view as increasingly authoritarian and dismissive of opposing views.(AP Photo)
