Hong Kong anti-government protesters set fire to shops and hurled petrol bombs on Sunday, police said, after riot police fired tear gas and water cannon to disperse thousands in the Tsim Sha Tsui harbor-front hotel district.

The protesters, many in all-black clothing and face-masks now banned under a resurrected British colonial-era law, had gathered to denounce perceived police brutality during more than four months of often-violent unrest in the Chinese-ruled city.

There was a standoff as dusk fell, with protesters, bemused tourists and passers-by gathered on the pavements of the shopping and hotel artery of Nathan Road, which police had earlier cleared in slow-moving cordons.
