Hong Kong police officer fired a gunshot during protests on Sunday, this was the first time a live round has been used since demonstrations broke out in June.
Images show several other officers also pointed guns at protesters who were chasing them with sticks.
Police told local media that the gunshot was fired as a warning to protesters, and that several officers had been taken to hospital as a result of the clashes.
As tensions escalated on Sunday, black-clad protesters threw projectiles, including bricks and petrol bombs.
Police also fired rubber bullets and tear gas, and used two water cannon vehicles to clear barricades and disperse crowds.
The protests began in the city’s Tsuen Wan district and have since spread to the district of Tsim Sha Tsui.
Demonstrations were sparked by an extradition bill but have since morphed into broader anti-government protests, and developments on Sunday mark a serious escalation in the unrest.
Activists have criticised the police for being heavy-handed during the pro-democracy rallies.
Several people were hospitalised on Saturday as well after violent clashes.
The latest round of violence comes after an uneasy peace that lasted a little more than a week.
