Hong Kong police fired rubber bullets and tear gas in running clashes with protesters late on Sunday, amid chaotic scenes as anger over an extradition bill morphs into a fresh front against what many see as a broader erosion of freedoms by Beijing.
Hundreds of riot police faced off with protesters more than a kilometre from the Liaison Office, firing tear gas as police and ambulance sirens echoed through the chanting crowds.
Local broadcaster RTHK and other local media reported police also fired rubber bullets, while protesters fought back or counter-attacked with bottles, bricks, poles, and umbrellas.
Millions have taken to the streets in the past two months in an unprecedented show of force against Hong Kong leader Carrie Lam, triggering the worst social turmoil to rock the former British colony since it returned to Chinese rule 22 years ago.
The protests have at times paralysed parts of the financial district, shut government offices and disrupted business operations across the city. Officials have also warned about the impact of the unrest on the economy.
