Hong Kong police have used tear gas to disperse thousands of pro-democracy protesters near the government complex, after a week of escalating tensions.
Dozens of demonstrators were arrested, with hundreds vowing to stay put to continue the protest.
Protesters want the Chinese government to scrap rules allowing it to vet Hong Kong's top leader in the 2017 poll.
