In Hong Kong, a general strike has paralyzed the city’s transportation and shut down many businesses and large parts of the service industry as pro-democracy protesters escalate their demands. Hundreds of flights have also been canceled. Demonstrators took to the streets over the weekend, blocking major roads, with riot police firing tear gas at crowds and arresting at least 80 people.

The popular uprising started nine weeks ago to demand the withdrawal of an extradition bill that would have sent people from Hong Kong to mainland China to face charges, but demands quickly grew for the resignation of Hong Kong’s leader Carrie Lam, an investigation into violence against demonstrators, and pro-independence reforms. Carrie Lam warned Hong Kong is being pushed to “the verge of a very dangerous situation.”
