(SOUNDBITE) (English) CARRIE LAM SAYING:
"We are now in extensive and serious public danger."
And with that, Hong Kong's leader Carrie Lam announced she would invoke sweeping new emergency powers in an attempt to stop the city's months of violent unrest.
And this was the scene as night fell.
This is the first time in over 50 years that Hong Kong has used its emergency laws, which allow the city to stop the protests by any means necessary.
That includes curfews, censorship of the media, and control over transport hubs.
For now it seems the city has only banned face masks. It's not yet clear what else may be employed.
(SOUNDBITE) (English) HONG KONG PROTEST LEADER JOSHUA WONG SAYING:
"The world must stand with Hong Kong against Hong Kong being transformed into a police state with martial law."
That was Joshua Wong, one of the city's most high-profile activists against Chinese rule.
The face mask ban can carry a maximum fine of roughly $3,200 and a year in prison if a person refuses to remove their mask when asked by police.
It's very common for people in Hong Kong and mainland China to wear masks every day to protect against the spread of disease.
Violence in this city has escalated to a new level in recent days following the police shooting of a teenage protester during one violent skirmish.
More rallies are expected over the weekend.
