Turkish police fired massive volleys of tear gas and jets of water to disperse thousands of anti-government demonstrators in Istanbul's Taksim Square on June 11, after earlier apparently retreating, an AFP reporter saw. The gas sent the crowd scrambling, raising tensions on a 12th day of violence after Prime Minister Recep Tayyip Erdogan warned he had &quot;no more tolerance&quot; for the mass demonstrations.
