Hong Kong has seen a second day of violent clashes between police and pro-democracy demonstrators who are also angry at alleged police brutality.
Police fired tear gas at protesters near the Chinese government’s office and in a busy shopping district.
Tens of thousands of demonstrators have taken over streets near Sai Wan and Causeway Bay on Hong Kong Island.
Hong Kong has seen eight consecutive weekends of anti-government and pro-democracy protests.
Sunday’s protests saw activists wearing protective helmets and goggles erecting barricades at several different locations and chanting “free Hong Kong”.
Police had earlier warned that such protests would be illegal.
The previous day police fired tear gas and rubber bullets at another pro-democracy protest in Yuen Long, in the north.
Hong Kong is ranked as one of the safest cities in the world – but recent protests have been followed by violent clashes between demonstrators, police and masked men wielding sticks suspected of being criminal gang members.
Police had authorised a static sit-in at Chater Gardens, a public square in the central business district, on Sunday – but did not permit a march, citing safety concerns.
However, the rally quickly spilled out from the square, with protesters blocking roads and marching towards Sai Wan, where the Chinese government’s offices are based, and Causeway Bay, a downtown shopping area.
Some protesters chanted “reclaim Hong Kong” and “revolution of our times”, or held up banners that read “end the violence”.
An act of mass defiance

Protestors have barricaded themselves into the streets of the Causeway Bay shopping area.
Under neon lights advertising makeup and jewellery they wait with helmets and gas masks for what they believe will be the inevitable assault from riot teams.
Tourists carrying shopping bags, including many from mainland China, continue to walk the streets of Causeway Bay as activists shout slogans in favour of democracy.
How did we get here?
Demonstrations began when the Hong Kong government introduced a controversial bill that would have enabled extraditions to mainland China.
It sparked huge protests as critics feared the bill would undermine Hong Kong’s freedoms, and be used to target political activists.
The row intensified as police were accused of using excessive force on anti-extradition bill protesters.
Tensions increased further last Sunday, when suspected triad members descended on a subway station in Yuen Long, beating protesters, passersby and journalists with sticks.
Demonstrators accused the police of colluding with the triads – claims angrily denied by the police.
The authorities say they have arrested 12 people over the attack, including nine men with links to triads.
The anti-extradition protests have morphed over time into a wider movement.
While the government has paused work on the extradition bill, protesters now want it withdrawn completely, as well as an independent inquiry into police violence, and democratic reform.
They want the territory’s leader, Carrie Lam, who is not democratically elected, and whose handling of the crisis has been widely criticised, to resign.
Some protesters have also expressed their anger at the mainland Chinese government, which they say has been eroding freedoms in Hong Kong.
Last week, demonstrators stormed the Chinese government’s office and defaced the national emblem.
The authorities have now installed a protective casing around the sign.
Could the Chinese military get involved?
As a former British colony, Hong Kong has its own legal and judicial systems, and has been promised “a high degree of autonomy” from the Chinese government, except in foreign and defence affairs.
China’s People’s Liberation Army (PLA) does have troops stationed in Hong Kong, but they are not expected to interfere in local issues.
However, the law does permit Hong Kong’s government to request assistance from the PLA for purposes of maintaining public order, or disaster relief.
Earlier this week, while condemning protesters who had vandalised the Chinese government’s offices, China’s defence ministry spokesman said that there were “clear stipulations” in the law allowing Hong Kong’s leaders to ask the army for help.
Hong Kong’s government and police have stated in recent weeks that they have no plans to involve the army – while some commentators argue that China would consider using its troops in Hong Kong to be too politically risky.
