Greeks confirm three cases of bird flu in swans, By Lefteris Papadimas

ATHENS (Reuters) - Greece on Saturday reported cases of H5N1 bird flu in three dead swans, as the disease appeared to have been spread into the European Union by wild birds.

"This is the deadly, the aggressive strain of the virus," Deputy Agriculture Minister Alexandros Kontos told Reuters. "The swans were probably flying to Africa because of the cold snap in central Europe."
