Protesters and riot police took to the streets of Hong Kong. Police launched tear gas at the crowd when tensions boiled over. They held up warning signs telling the crowds to disperse, which was followed by more tear gas and arrests. One rally of pro-democracy protesters carried U.S. flags and posters in a march to the U.S. consulate in a "march of gratitude." Days ago, U.S. approved legislation that would sanction Hong Kong and Chinese officials for any human rights abuses.
