DHAKA: Hong Kong police have clashed with protesters again, with the government saying 20 people were injured in a fourth night of violence after nearly three weeks of pro-democracy rallies.

Dozens of police with shields and helmets pushed into a crowd of protesters gathered at barricades in the shopping district of Mong Kok early on Sunday, striking at them repeatedly with batons, Aljazeera.com reports. 

Police said in a statement that they had used "minimum force" as protesters "suddenly attempted to charge" their cordon lines.

The city's government information service said 20 people involved in protest activities had been injured between 10pm and 6am, but would not specify how many were demonstrators or police, the extent of the injuries, or if they all took place in the Mong Kok area.
