A policeman has shot at least one person in protests during on Monday morning rush hour in Hong Kong.
Footage shown live on Facebook showed the officer drawing his gun before grappling with a man at a roadblock.
Another man, wearing a face mask, then approaches and the officer shoots him, hitting him in the torso.
As the grapple continues, the officer fires another two rounds-although it's not clear from the footage whether the bullets hit anyone.
The condition of the first person shot is not known. Footage showed him lying on the ground, eyes open, with blood around him.
It's the third time police have shot someone with live rounds since Hong Kong protests began in June.
The first incident was during protests on 1 October when China was celebrating 70 years of communist rule. The second case was a teenage boy shot in the leg on 4 October.
The Monday morning shootings happened as protesters tried to block a junction at Sai Wan Ho no the north-east of the istand.
Protesters used barricades to block roads in various areas, leading to long traffic jams. Some train and subway lines were also disrupted.
The latest violence comes after a student died on Friday after falling from a ledge in a car park, reportedly trying to flee from police tear gas.
Hong Kong is part of China but as a former British colony, it has some autonomy and people have more rights.
The protests started in June against plans to allow extradition to the mainland-which many feared would undermine the city's freedoms.
The bill was withdrawn in September but demonstrations continued and now call for full democracy and an inquiry into police behaviour.
Clashes between police and activists have become increasingly violent and in October the city banned all face masks. Source: BBC
