HANOI (AFP) - Bird flu has spread to another northern province in Vietnam, bringing to nine the number of localities hit by the deadly virus, the government said Sunday.
Some 250 fowl died Friday at a farm in Hoa Lu district of Ninh Binh province, 100 kilometers (62 miles) south of Hanoi, the national animal health department said on its website.
The rest of the almost 2,000-strong flock were culled immediately after test results showed they were carrying the H5N1 virus, it said.
Bird flu outbreaks have now been reported in provinces across Vietnam, with the north the worst affected.
