Authorities in Hong Kong have shut down government offices and postponed debate in the Legislative Council, one day after riot police fired tear gas, rubber bullets and pepper spray at tens of thousands of demonstrators who took to the streets to protest a bill that would allow the extradition of Hong Kong residents to mainland China. On Wednesday, demonstrators attempted to storm the Legislative Council Building, where lawmakers are debating the extradition bill. Human Rights Watch criticized Hong Kong authorities for using what it described as “excessive force” to suppress peaceful demonstrations. Protesters described police using indiscriminate force. We speak with Mary Hui, a Hong Kong-based writer and reporter for the news outlet Quartz. She has reported on the extradition bill and has been covering the protests.
