" Half a million chickens are to be culled in a district on the outskirts of Nepal's capital Kathmandu, as efforts to combat a major outbreak of bird flu are stepped up.
Tens of thousands of birds have already been killed in what government officials have described as one of the country's worst outbreaks of avian flu.
Now authorities in the Himalayan nation have declared the area of Bhaktapur an emergency zone.
Some 62 cases of bird flu have been recorded at 250 poultry farms in three districts in the past few weeks, officials said.
A spokesman for the Directorate of Animal Health said the government ordered the cull to be stepped up after a week-long ban imposed on the sales of poultry products failed to control the H5N1 virus."
