Protesters carrying umbrellas brave pepper spray used by riot police as tens of thousands of demonstrators block the main street to the financial Central district outside the government headquarters in Hong Kong September 28, 2014. Hong Kong police used tear gas for the first time on Sunday to disperse pro-democracy protests and baton-charged the crowd blocking a key road in the government district after Hong Kong and Chinese officials warned against illegal demonstrations. Police had not used tear gas in Hong Kong since 2005, to break up World Trade Organization protests against South Korean farmers. REUTERS/Bobby Yip (CHINA – Tags: POLITICS CIVIL UNREST) – RTR480DA
