Hong Kong police on Monday defended pulling out their guns and firing a warning shot during anti-government protests over the weekend, and lawmakers on each side of the city's political divide said the other side bears responsibility for the violence.
Assistant Police Commissioner Mak Chin-ho said one officer fired into the air and six held up their revolvers after protesters charged them repeatedly with metal poles, long sticks and road signs on Sunday night.
"Their use of force was indeed necessary and reasonable," he told a news conference at police headquarters.
Pro-government lawmakers condemned the acts of protesters who blocked streets, threw gasoline bombs and assaulted police officers.

"You can say a lot of different opinions to the government," said Starry Lee, chairwoman of the Democratic Alliance for the Betterment and Progress of Hong Kong. "But violence is different. If we can accept violence, our city will be ruined."
Pro-democracy members of the Legislative Council countered that the government and the police need to take responsibility, the former for introducing the extradition legislation that sparked the protests and the latter for what they say is selective enforcement of the law targeting government opponents.
Kwok Ka-ki, a member of the Civic Party, blamed Hong Kong leader Carrie Lam. He called her creation of a platform for dialogue a delay tactic rather than an attempt to resolve the conflict.
"She is the one who should shoulder all the responsibility, and now she is trying to get away from all the responsibility and shifting the focus to the so-called platform," he said.
At a government news conference, Matthew Cheung, the chief secretary for administration, said the protesters' actions show a total disregard for law and order and called them unacceptable. On Saturday, protesters damaged several "smart" lampposts installed by the city, cutting at least one down with a circular electric saw.
"We need to have dialogue instead of confrontation," Cheung said, according to a simultaneous translation of his remarks. "We need to have peace instead of violence."
A hard-line contingent of protesters took over streets on Saturday and Sunday following peaceful pro-democracy marches. They argue that peaceful protests are not enough to get the government to respond to their demands. Police used tear gas to clear the streets and arrested more than 80 people.
The movement has five demands including democratic elections and an independent inquiry into what it alleges is police violence in breaking up demonstrations.
The protests started in early June with the now-suspended extradition bill, which would have allowed suspects to be sent to mainland China to face trial, and has expanded to encompass a general concern that China is chipping away at the rights of Hong Kong residents.
Hong Kong's leader is chosen by a 1,200-member committee dominated by supporters of the central government in Beijing. About half of the legislature is elected
