Russian officials say the deadly H5N1 strain of the bird flu virus has killed more than 100,000 birds on a poultry farm in southern Russia.

The governor, Alexander Tkachev, of the Krasnodar region said Tuesday that the farm has been quarantined and other measures have been ordered to stop the spread of the virus.

In Paris, the World Organization for Animal Health warned that the H5N1 virus would likely spread across Europe after being found at a French poultry farm.

Officials were holding a second day of talks in the French capital to discuss mass vaccinations and other efforts to combat the illness.

Meanwhile, Swedish authorities say wild ducks in southern Sweden have been found with the H5 strain of bird flu.

And Pakistani authorities today culled at least 15,000 chickens infected with the H5 strain in North West Frontier province.
