Captive tigers killed by bird flu

More than 20 tigers have died from bird flu at a private zoo in Thailand after being fed the carcasses of chickens infected with the disease.

The 23 big cats had been dying at the Sriracha Tiger Zoo in central Chonburi province since September 14, and the animal park was forced to close its doors to the public while authorities investigated, said Charal Trinvuthipong, director of the Bird Flu Prevention and Elimination Centre.
