Police have fired tear gas to try to disperse a demonstration in Hong Kong as protesters took over streets in three parts of the Asian financial capital, blocking traffic and setting up another night of likely showdowns with riot officers.

The Hong Kong authorities began destroying 15,000 chickens at a poultry market and suspended imports from mainland China after some birds were found to be infected with bird flu.
