Peru has reported an outbreak of the highly pathogenic avian influenza virus on a laying hens farm in the department of La Libertad in the northwestern part of the country, Reuters reported, citing the Paris-based World Organisation for Animal Health (WOAH) on Tuesday.

The virus killed 4,000 birds and the rest of the 27,000-strong flock were slaughtered, WOAH said, citing a report from the Peruvian authorities.
