India has confirmed an outbreak of bird flu following the death of thousands of chickens in the past week in West Bengal.
The birds tested positive for the potentially deadly H5N1 strain.
It is the third outbreak since 2006 and the first since India declared itself free of the disease last November.
The deaths were reported from farms in Morgram village, about 125km from the state capital, Kolkata.
An isolation centre has been opened in a hospital near the affected village and 300 health workers have been sent there with medicines and protective gear.
All poultry within 5km of Margram are to be culled.
The disease has killed more than 200 people worldwide since 2003.
West Bengal borders Bangladesh, where authorities have been struggling to contain an outbreak of the virus.
In Indonesia, a 16-year-old girl has the country's 96th victim of the flu.
Warning to Irish farmers
Poultry farmers in the Republic have been warned to be extra vigilant after three dead swans in a bird sanctuary in Dorset, England, were found to have H5N1.
The Department of Agriculture and the Irish Farmers' Association reminded poultry-keepers to remain on alert.
The IFA says the potential for infection among commercial flocks is very low, but farmers should continue to be aware of the risks after the UK's Department for Environment, Food & Rural Affairs confirmed avian influenza in the wild mute swans in Abbotsbury, near Chesil Beach, Dorset.
A surveillance programme is under way to determine whether the virus, which can pass to humans, has infected other wild birds and ducks at the bird sanctuary. So far no disease has been found in domestic birds nearby.
About 800 swans, as well as other birds, feed and breed in the nature reserve's wetlands.
