Police fired pepper spray to disperse protesters who gathered in Hong Kong's working-class district of Mong Kok on Thursday night to mark the 31st anniversary of China's bloody crackdown on democracy students at Tiananmen Square, witnesses said.
Earlier, thousands defied a police ban to gather with candles across the former British colony to remember the 1989 violence and accuse Beijing of stifling freedoms too on their semi-autonomous territory.
