Riot police disperse Turkey protesters

Riot police fired water cannons and tear gas as they drove protesters out of Istanbul's Taksim Square and neighboring Gezi Park on Saturday, an intervention that came shortly after the prime minister warned that security forces "know how to clear" the area, which had become a symbol of the biggest anti-government protests in decades.   Within a half-hour, the sweep by white-helmeted riot police had emptied the park, leaving a series of colorful, abandoned tents behind. Protesters put up little physical resistance, even as plain-clothes police shoved many of them to drive them from the park.
