Armed with wooden poles and ransacked road signs, pro-democracy protesters and their opponents fought an extraordinary battle on a Hong Kong street, exposing deep ideological fault lines coursing through the city.

The shocking scenes — captured on film — showed the demonstrators fighting back against the men, pelting them with traffic cones and even turning their aggressors' weapons against them.
Cars, including taxis and a Mercedes-Benz, were also caught up in the melees as both sides fought over street fencing dividing the thoroughfare.
The men were eventually chased away, with protesters smashing the windows of a nearby building where they believed some of the attackers had taken refuge as a man inside brandished a meat cleaver.
The clashes illustrate the polarisation of Hong Kong after two months of pro-democracy protests and clashes that pose the biggest threat to Beijing's authority since Hong Kong's handover from the British in 1997.
North Point, a district on the main island where the clashes took place, was historically a communist stronghold during British rule.
It is known for its large community of Fujianese people who migrated from the mainland province in the 1960s and have long maintained strong family and clan links there.
Troubled past
During the 1967 leftist riots -- in which more than 50 people died -- North Point was often the epicentre of the violence.

Police famously landed by helicopter on the roof of an apartment building and discovered a leftist headquarters.
The riots were sparked by widespread social discontent towards the colonial government over widespread corruption and poverty. But they were also fuelled by the influence of the Cultural Revolution which was raging on the mainland at the time.
Popular opinion soon turned against the leftists who left hundreds of bombs across the city and murdered a well-known anti-communist radio commentator. Two young children were killed by a bomb left in North Point.
