HONG KONG--Hong Kong's government said violence and illegal protests were pushing the city to an "extremely dangerous edge", as police fired multiple rounds of tear gas to disperse hundreds of anti-government protesters on Sunday and Beijing said it would not let the situation persist.
The Chinese-controlled city, an Asian financial hub, has been rocked by months of protests that began against a proposed bill to allow people to be extradited to stand trial in mainland China and have developed into calls for greater democracy.
A general strike aimed at bringing the city to a halt is planned for Monday. Many flight departures were shown as being cancelled on Monday and a source and media reports said this was due to aviation workers planning to strike.
Late on Sunday, hundreds of masked protesters blocked major roads, spray painted traffic lights, started fires and prevented transport from entering the Cross-Harbour Tunnel linking Hong Kong island and the Kowloon peninsula. "We sprayed the traffic light because we don't want traffic to work tomorrow and we don't want citizens to go to work," said one protester who was clad from head to toe in black.
Riot police confronted the protesters, who have adopted flash tactics, shifting quickly from place to place to evade capture and using online platforms such as Telegram to direct hundreds of people.
In a strongly worded statement late on Sunday the government said the events of the day showed once again that violence and illegal protests were spreading and pushing Hong Kong toward what it called "the extremely dangerous edge." Such acts had already gone far beyond the limits of peaceful and rational protests and would harm Hong Kong's society and economic livelihood, it said.
After the peaceful demonstrations finished earlier on Sunday, protesters blocked roads in the town of Tseung Kwan O in the New Territories, set up barricades and hurled hard objects including bricks at a police station. Police fired tear gas to disperse hundreds of protesters after a separate rally in the island's Western district where thousands of people gathered to urge authorities to listen to public demands. Protesters had begun a march towards China's Liaison Office, which has been a flashpoint at previous protests.
Later on Sunday night, police fired tear gas in the shopping area of Causeway Bay to dispel protesters, forcing stores and popular shopping malls including Times Square to close early.
Police said the protesters were "participating in an unauthorised assembly", similar to Saturday when they fired multiple tear gas rounds in confrontations with black-clad activists in the Kowloon area.
The protests have become the most serious political crisis in Hong Kong since it returned to Chinese rule 22 years ago after being governed by Britain since 1842. They have also presented the biggest popular challenge to Chinese leader Xi Jinping in his seven years in power.
China's official news agency Xinhua said on Sunday: "The central government will not sit idly by and let this situation continue. We firmly believe that Hong Kong will be able to overcome the difficulties and challenges ahead."
During the night, protesters split into several different directions to disrupt transport networks. Police said they were "seriously paralysing traffic and affecting emergency services" and warned them to stop immediately.
The leaderless nature of the protests has seen participants adopt a strategy called "be water", inspired by a maxim of the city's home-grown martial arts legend, Bruce Lee, that encourages them to be flexible or formless. Police said more than 20 people had been arrested since Saturday for offences including unlawful assembly and assault.
