At least 79 people, including 26 members of the Turkish security forces, were injured in the clashes across the country, Interior Minister Muammer Guler told Turkey's semi-official Anadolu news agency on Saturday. Among the injured were 14 in Istanbul, including one who suffered brain trauma, the Istanbul governor's office said. Turkish authorities have detained 939 people in connection with the protests, Guler told Anadolu. A peaceful sit-in on Friday against government plans to demolish a park was met with a police action, according to a report of CNN. Turkish police retreated from Istanbul's central Taksim Square on Saturday afternoon, allowing tens of thousands of demonstrators to pour into the space.
