Hong Kong riot police fire tear gas as hundreds of protesters march along a downtown street during a pro-democracy protest against Beijing's national security legislation in Hong Kong, Sunday, May 24, 2020. Hong Kong's pro-democracy camp has sharply criticised China's move to enact national security legislation in the semi-autonomous territory. They say it goes against the "one country, two systems" framework that promises the city freedoms not found on the mainland. (AP Photo/Vincent Yu)
