Hong Kong: Police violently tackle suspected protesters on metro
Riot police have clashed with suspected protesters in Hong Kong's metro system after thousands marched in defiance of a ban.
Protesters lit fires, threw petrol bombs and attacked the parliament building.
In response, police used tear gas, rubber bullets and water cannon to disperse crowds, and fired live warning shots as they tried to clear the streets.
Hong Kong has now seen 13 successive weeks of demonstrations.
