Beijing and the Chinese army have issued stern warnings about the unrest.
Two months of demonstrations sparked by a controversial extradition bill show no signs of abating, with both sides hardening their stance.
Although the government has now suspended the bill, which would have allowed extraditions to mainland China, demonstrators want the bill fully withdrawn.
Their demands have broadened to include calls for more democracy and for Hong Kong’s leader Carrie Lam to resign.
…Saturday’s march comes after a group of civil servants – ordered to be politically neutral – joined demonstrations in their thousands on Friday.
The rally followed the publication of an anonymous letter on Facebook complaining about “extreme oppression” and listing five key demands – the complete withdrawal of the extradition bill; waiving charges against those arrested; an end to descriptions of protests as “rioting”; an independent inquiry into the unrest; and resuming political reforms.
…More than 40 activists appeared in court on Wednesday, charged with rioting after protests last Sunday turned violent.
They could face up to 10 years behind bars if convicted.
Tensions rose further when the military – which has not yet intervened in the unrest – posted a video on social media network Weibo showing soldiers conducting anti-riot drills.
