Riot police fired multiple volleys of tear gas Sunday to disperse pro-democracy protesters close to Beijing's office in Hong Kong, plunging the financial hub deeper into crisis.

The clashes are the second consecutive day of violence in a city reeling from weeks of anti-government protests that show no sign of abating.

Sunday's clashes took place close to the Liaison Office, which represents Beijing in the semi-autonomous hub and which was pelted with eggs and paint last week.
