Police have fired rubber bullets and tear gas at protesters in Hong Kong where anger at a new extradition bill has spilled over into violence.

Protesters blocked key roads around government buildings and threw bricks and projectiles at police.

The government is still pushing for the bill which would allow extradition to mainland China and it is expected to pass its final vote on 20 June.

But the Legislative Council (LegCo) has now delayed its second reading.
