Protests in Hong Kong show no sign of stopping, as hundreds of thousands of demonstrators continue to demand greater autonomy from the government in Beijing.

Tomorrow is National Day, a public holiday across China. Activists say there’s a chance the protests could swell even beyond what you can see in this video.
