Tear gas fired in new Hong Kong protest as police vow 'to bring all culprits to justice'

Hong Kong police have used tear gas to disperse protesters outside a police station, hours after flights resumed at the city’s airport following two days of disruption that descended into clashes between demonstrators and officers.

In the blue-collar Sham Shui Po area, police fired tear gas on Wednesday night at a group of protesters rallying outside the station.
