Speaking to the press Monday afternoon, Hong Kong's Chief Executive Carrie Lam said that the government would not yield to protesters demands.
"If there is any wishful thinking that by escalating violence the (Hong Kong) government will yield to pressure to satisfy protesters' so-called demands, I'm making this clear that will not happen," she said.
Lam added that violence would not offer any solutions "to the problems facing Hong Kong."
"We will spare no effort in finding ways and means that could end the violence in Hong Kong as soon as possible," the city's leader said.
Lam warned members of the public to stay away from areas where "unlawful activities" were taking place.
On Monday, video footage and images from the ground showed people -- many office workers without masks or other protective gear -- coughing and doubled over, with some rushing into a subway station to escape the tear gas.
