<![CDATA[Violent clashes mar protest after 'more than a million' Hongkongers of all ages and backgrounds march against controversial extradition bill]>

Protesters used bottles and metal barriers to attack police who tried to drive them away with batons and pepper spray outside Hong Kong's legislature late on Sunday night at the end of mass rally that drew historic numbers against the government's highly contentious extradition bill.

Hundreds of diehard remnants of the daytime march remained camped out in front of the government headquarters compound into the night, with more joining them in response to calls from student group Demosisto and pro-independence radicals to surround the Legislative Council building.

A stand-off with police descended into chaos as protesters tried to storm the compound.

Bottles were thrown during pitched battles and at least one officer could be seen with a bloodied face, while some protesters were beaten with batons or wrestled to the ground and taken away.

Organisers declared the turnout to be more than 1 million, double that of the 2003 mass rally that led to the city's then leader stepping down.

It was the strongest display of people power to challenge the leadership of embattled Chief Executive Carrie Lam Cheng Yuet-ngor as wave upon wave of protesters washed over the northern part of Hong Kong Island, disrupting or bringing traffic to a grinding halt from early afternoon to late at night, as they made their way through the canyon of skyscrapers from Victoria Park to the Legislative Council.

Such was the size of the crowds that they were still flocking to the rallying point long after the first marchers had left, and the tail end of the rally was still in Causeway Bay as night fell.

Many others trying to join were unable to because of police crowd-control measures, as train stations were swamped and traffic was chaotic with some drivers even leaving their cars on the road.

Organising group Civil Human Rights Front claimed a historic turnout at 1.03 million, while police reduced it to a more conservative estimate of 240,000 at its peak.

At the July 1 rally in 2003, police estimated the number was 350,000 before its peak, while organisers claimed it was more than 500,000. That public backlash against the government's push for national security legislation prompted then chief executive Tung Chee-hwa to step down.

This time, the city's leader has vowed not to back down, with enough votes promised by her political allies in Legco to pass her bill, which would allow the transfer of fugitives to mainland China and other jurisdictions with which Hong Kong has no extradition deal.

"Will anyone still believe Carrie Lam any more if she continues to claim there is only a small number of people opposing the bill?" said former opposition lawmaker Margaret Ng Ngoi-yee, among the hundreds of pan-democrat leaders and activists at the rally.

Describing Sunday's march as a new start for Hong Kong, she said: "We have so many groups, so many schools, even housewives, new migrants, horse racing fans ... so many different groups joined the protest on their own initiative."

Protesters also chanted slogans demanding Lam's resignation.

"Down, down, Carrie Lam," and "No extradition to China," they shouted.

The chief executive chose to spend her Sunday officiating a ceremony at Ocean Park.

A government source said the extradition bill would still be put before Legco for debate and a vote, regardless of the turnout.

He pointed out 710,000 people had added their names to a signature campaign to support the bill and their voices could not be ignored.

A government spokesman said it had listened carefully to different views on over the past four months and made two revisions.

The government is expected to table the bill for its second reading on June 12, bypassing the usual process of scrutiny by a bills committee, and hopes to have it passed by the end of the current legislative term next month.

Lam and her top officials have repeatedly stressed there are provisions under the law to stop people from being persecuted for political or religious beliefs, and that Hong Kong's judiciary can play the role of gatekeeper for fugitive transfer requests.

Front convenor Jimmy Sham Tsz-kit said: "It is not the end of the story. If the government continues to refuse to heed the people's voices, there will be more and bigger protests."

He said protesters would be mobilised to besiege Legco next in the coming days.

The rally was largely peaceful, except for isolated scuffles and some rogue incidents.

Police had to use pepper spray at one point as several masked protesters ran out onto the road and tried to block traffic outside government headquarters in Admiralty.

Earlier, seven men were arrested for criminal damage, theft, and assault during the march.

Hundreds of diehard protesters remained at the Admiralty finishing point long after the rally officially ended at around 10pm.

Some sat in front of the metal barricade to block the car park entrance to the legislature in a stand-off with police.

Opposition to the bill went global on Sunday, with similar protests being staged in 29 cities in 12 countries and regions, from New York and London to Tokyo and Taipei, mainly by Hongkongers living overseas.

With Beijing officially throwing its weight behind Lam to push the bill, it was unlikely to have a change of heart after Sunday's rally, according to Lau Siu-kai, a vice-chairman of semi-official think tank The Chinese Association of Hong Kong and Macau Studies.

"The issue now is more than the extradition bill. To the Beijing leaders, it is a showdown between China and foreign influence," he said, referring to the campaign against the bill by Western business chambers and consulates.

"Unlike the 2003 protest when it was Beijing versus the Hong Kong opposition camp, this time, it is Beijing versus the US and its allies."
