Bird flu kills 25,000 turkeys in eastern Poland, sparks cull

Authorities in eastern Poland say bird flu is responsible for the deaths of at least 25,000 turkeys in poultry farms near the country's borders with Ukraine and Belarus

Polish veterinary authorities on Thursday were planning to cull tens of thousands of birds in the Lubartow area, a major poultry farming region. Police were blocking access to the affected area to non-residents.

It was not clear how the bird flu virus found its way to the farms.
