Thousands of protesters and police in Hong Kong are engaged in a standoff as anger grows over a bill which would allow extradition to mainland China.
Early on Wednesday protesters, some wearing face masks and helmets, blocked key roads around government buildings.
Police in riot gear responded by using pepper spray on protesters to disperse them and said they were prepared to use force.
The Legislative Council (LegCo) has now delayed the second reading of the bill.
The pro-Beijing LegCo released a statement on Wednesday saying that the meeting which was planned for 11:00 local time (03:00 GMT), would be "changed to a later time" adding that members would be notified of the time later.
Despite widespread opposition the government had said it will continue to push for extradition.
A final vote is expected on 20 June with LegCo expected to pass the bill, Hong Kong media report.
