Fights erupted in Hong Kong on Saturday with political rivals trading blows in a mall and
Beijing supporters using Chinese flags to assault opponents on a street, deepening the city's polarisation after months of pro-democracy protests.
The once-stable international hub has been convulsed by weeks of huge, sometimes violent rallies calling for greater democratic freedoms and
police accountability.
The movement is the biggest challenge to China's rule since the city was handed back by
Britain in 1997 and shows no sign of ending, with city leaders and Beijing taking a hard line.
