Poultry farms around Moscow have been placed under tight control after a third outbreak of bird flu. Experts are trying to establish whether it is the H5N1 strain of the disease which can kill humans. More than 30 dead birds were discovered in two villages in the region around the capital.
People who were in contact with the animals have been taken to hospital as a precaution. One veterinary official said all transport in and out of the affected areas was being checked, but added that the situation was under control. It is the second bird flu outbreak in Russia this year and the first ever recorded close to the capital. The H5N1 virus killed poultry in three settlements in the southern region of Krasnodar last month.
