US on Hong Kong Protests: 'No More Violence on Both Sides' Nike Ching VOA Mandarin Service, Ken Bredemeier, Chris Hannas and Megan Duzor contributed to this article. The United States is calling for calm on all sides in Hong Kong, as protests took a violent turn in recent days and U.S. officials noted signs of softening among Hong Kong government and pro-democracy demonstrators. Hong Kong police fired volleys of tear gas to break up anti-government protests on Saturday, as protesters threw petrol bombs and bricks. "We can't sit quiet for more violence," a senior State Department official told VOA on Tuesday. "No more violence on both sides," either from the police or from the protesters, said the official. "Certainly, not any large-scale response through violence." .
