After two months of demonstrations, Hong Kong ground to a halt Monday during a violence-filled general strike that saw protesters blocking trains during the morning rush hour and more than 200 flights getting canceled when ground workers walked off the job, according to reports.

Police fired tear gas and rubber bullets at protesters who set fires and lobbed bricks at officers.

Hong Kong is on “the verge of a very dangerous situation,” said Chief Executive Carrie Lam, the Beijing-backed leader who insisted that she has no plans to resign despite the tumult rocking the former British colony.

Public broadcaster RTHK reported Monday that domestic carriers such as the flagship Cathay Pacific and Hong Kong Airlines were the most affected. Cathay Pacific advised passengers to postpone non-essential travel.

The Airport Express train, which links the city’s business district to the airport, also was out of service.

“Why do they have to create trouble for people not involved in their cause?” said John Chan, whose flight to Singapore was canceled. “Hong Kong is sinking. The government, police and protest people have to stop fighting and give us a break.”

Protesters also snarled the morning rush hour by blocking train and platform doors to prevent trains from leaving stations. Subway and train operator MTR said service had been partially suspended on four lines because of several door obstruction incidents.

Members of the Hong Kong Disneyland Cast Members Union also went on strike, as did many lifeguards, forcing some beaches and swimming pools to be closed.

What began as protests over an extradition bill that would have let people be sent to mainland China to face trial have evolved into a much broader backlash against the city government and its political masters in Beijing.

While the government has since suspended the bill, demonstrators have pressed on with broader calls for democratic reforms, including the dissolution of the legislature and a probe into alleged police brutality.

The protests are the greatest political threat to the territory, which Britain returned to China on July 1, 1997, and one of the biggest popular challenges to Chinese leader Xi Jinping since he came to power in 2012.

Lam told reporters that the protesters had “ulterior motives” that threaten Hong Kong’s prosperity and security.

“I don’t think at this point in time, resignation of myself or some of my colleagues would provide a better solution,” she said.

Demonstrators challenged authorities in at least eight districts, throwing gas canisters back at police, yelling invectives and pounding on metal street signs as they dared the cops to move closer.

“Gangsters!” they jeered at the riot police, who sent at least 24 protesters to hospitals. “Reclaim Hong Kong, revolution of our time!”

Police said they were using “minimum force” to remove the demonstrators, whom they assailed for “blocking roads extensively and setting fire to miscellaneous objects,” according to CNN.

“The protesters are surrounding and attacking various police stations and the adjacent (barracks), hurling igniting objects and hard objects, making damages to the premises,” the statement said.

Meanwhile, Amnesty International condemned the alleged sexual assault of a female protester by the police late Sunday.

“We condemn the police’s brutality and disproportionate use of force in handling the subdued protester. The female protester’s clothing was pulled up, exposing her private parts,” the human rights group said in a statement.

Police spokeswoman Yolanda Yu Hoi-kwan said “the woman was wearing a dress and she struggled strongly, which explained what happened in front of the camera,” CNN reported.

Amnesty International insisted that “protesters’ clothing is not an excuse for the police’s sexual violence.”

At a daily briefing, Yu said 420 protesters have been arrested since June 9, when a massive march drew more than 1 million people and ushered in the protest movement.

Those being detained, ranging in age from 14 to 76, face charges including rioting, unlawful assembly, possessing offensive weapons and assaulting officers and obstructing police operations, Yu said.

Police have used 1,000 tear gas grenades and fired more than 300 non-lethal bullets, Yu said, adding that 139 officers had been injured in clashes, with two still hospitalized with fractures.

She said violence has been mounting, with demonstrators using gasoline bombs and fire, including sending a cart full of burning trash hurtling toward cops.

“We love Hong Kong and hope to restore public order. If we continue to tolerate and turn a blind eye to lawless behavior, the consequences will be undesirable for our citizens,” Yu said.

The Communist Party-led central government in Beijing has condemned the protesters and has accused unnamed “foreign forces” of inflaming the demonstrations out of a desire to contain the country’s development.

Many businesses shut as workers stayed home.

“Losing a bit of money now is not such a problem, (compared) with losing everything that the freedom of Hong Kong used to stand for,” Mark Schmidt, 49, a restaurant manager who closed Monday, told Reuters.
