Demonstrators have gathered at Hong Kong's airport, marking the start of three days of unauthorised rallies in the Chinese territory, APA reports citing BBC.
Activists dressed in black sat in the arrivals hall waving banners to raise awareness among international visitors.
Protests have gripped Hong Kong for weeks, beginning with anger at an extradition bill and morphing into demands for greater freedoms.
The former British colony is part of China but enjoys more autonomy.
It has a free press and judicial independence under the "one country, two systems" approach - freedoms activists fear are being increasingly eroded.
They have called for an independent inquiry into alleged police brutality during the protests, the complete withdrawal of the controversial extradition bill, and the resignation of Hong Kong's leader Carrie Lam.
Beijing has warned demonstrators not to "play with fire" or to "underestimate the firm resolve [of] the central government".
