Marathon:Strong winds and high temperatures were responsible for dozens of wildfires breaking out in Greece, officials said.
In Marathon, some 42 kilometres northeast of Athens, flames on Saturday were scorching a forested zone not far from the starting line of the Athens Classic Marathon race.
Greek authorities have declared a state of "red alert" for the weekend, with strong winds and a new heatwave continuing to grip Greece.
The winds were allowing the flames to spread before stretched fire-fighting teams could gain control. The fact that the fires took hold on land close to densely inhabited and resort areas was largely a matter of chance.
