HONG KONG POLICE use tear gas on pro-democracy protesters. “Hong Kong police used tear gas Sunday and warned of further measures as they tried to clear thousands of pro-democracy protesters who had gathered outside government headquarters in a challenge to Beijing over its decision to restrict democratic reforms for the semiautonomous city. . . . The demonstrations — which Beijing called ‘illegal’ — were a rare scene of disorder in the Asian financial hub, and highlighted authorities’ inability to rein in the public discontent over Beijing’s tightening grip on the city. The protesters reject Beijing’s decision last month to rule out open nominations for candidates under proposed guidelines for the first-ever elections for Hong Kong’s leader, promised for 2017.”
