Police use tear gas amid protest
Hong Kong police have used tear gas to try to clear a huge crowd of pro-democracy protesters who had gathered outside government headquarters.
Police lobbed canisters of tear gas into the crowd on Sunday evening after spending hours holding the protesters at bay.
The searing fumes sent protesters fleeing down the road.
Authorities launched their crackdown after the protest spiralled into an extraordinary scene of chaos as the crowd jammed a busy road and clashed with officers wielding pepper spray.
The protesters were trying tried to reach a mass sit-in being held outside government headquarters to demand Beijing grant genuine democratic reforms to the former British colony.
