Afghan authorities have ordered the slaughter of birds in areas where two cases of bird flu have been found.
The U.N.'s Food and Agriculture Organization said Wednesday birds carrying the virus have been reported in the eastern provinces of Nangarhar and Kunar. Officials suspect the cases are the deadly H5N1 strain of bird flu but do not yet have confirmation.
Last year, Afghanistan discovered cases of the H5N1 virus in birds, but not humans.
The deadly strain of the bird flu virus has killed at least 160 people worldwide since 2003.
