More than 1,000 anti-government activists gather in Mong Kok district as counter-protesters rally in support of police.

More than 1,000 people, mostly black-clad activists, gathered in Hong Kong’s Mong Kok district to take part in a protest march on Saturday, as the Chinese-controlled city braced for another weekend of anti-government demonstrations.

Protests for the past two months have grown increasingly violent, with police accused of excessive use of force and failing to protect protesters from suspected gang attacks.

Demonstrators have been calling against a proposed bill that would allow people to be extradited to stand trial in mainland China.

Police initially denied activists permission to march through the Mong Kok neighbourhood, but later allowed the rally to go ahead after an appeal.

“I’m a little worried about whether the police force might use violent ways on the demonstrators because the route of the demonstration is a little bit narrow, and if we want to leave it might be difficult to get away from the police,” said a 20-year-old university student named Ivan.

“I think this entire movement will continue until at least the end of 2019,” he said.

Mong Kok, a gritty working-class neighbourhood in the Kowloon section of the city, was the scene of some of the most violent clashes during pro-democracy protests in 2014.

Thousands of supporters of Hong Kong’s police, mostly wearing white, gathered for a separate rally on Saturday in Victoria Park in the Causeway Bay district of Hong Kong island.

“I really feel upset about the violence that we are seeing in Hong Kong every day. The protesters are now not listening to the government, they are not listening to the police,” said Evan, 27, who works for a foreign bank in Hong Kong and turned out in support of police.

“People have a right to express their opinion in a peaceful manner. We will continue to support the police and the authorities to implement rule of law here.”

Two anti-government marches are also planned for Sunday – one on Hong Kong island and the other in the Tseung Kwan O district.

A city-wide strike is planned for Monday and rallies in seven locations.

On Friday evening in central Hong Kong, thousands of civil servants defied a warning from authorities to remain politically neutral and joined anti-government protests for the first time since they started two months ago.

Meanwhile in Washington on Friday, a bipartisan group of US congresspeople called on the Trump administration to halt future sales of munitions and crowd-control equipment to Hong Kong’s police force.

Under Chinese rule, Hong Kong has been allowed to retain extensive freedoms, such as an independent judiciary, but many residents see the extradition bill as the latest step in a relentless march towards mainland control.

The protests are the most serious political crisis in Hong Kong since it returned to China 22 years ago.
