Lightning killed more than 50 sheep in the Vlacha area of Metsovo, northern Greece, during a thunderstorm that hit the area on Tuesday afternoon.
According to the state broadcaster ERT, the frequent thunderstorms that have erupted in recent days are especially strong with a lot of lightning.
Greece ranks first in the list of recorded deaths of people struck by lightning in Europe.
Last Saturday, as a result of a lightning strike on a group of climbers one athlete died and another was seriously injured.
“Unfortunately, Greece, statistically, probably has the highest number of deaths from lightning strikes than anywhere else in Europe,” Hellenic Rescue Team training director Zafiris Trombakas told state broadcaster radio.
