The Agriculture Ministry said thousands of domestic birds will be culled in the eastern villages of Braiesti, Tataru, and Padina.

That virus has already been confirmed in three villages in the nearby Danube Delta, a large wetland reservation where hundreds of thousands of migratory birds have arrived from Russia.
