A fire broke out Sunday afternoon in a pine forested expanse near Skalistiri, Elefsina.
The fire was in a difficult to access area, making approach by fire-fighting engines extremely difficult, according to the Fire Brigade.
Five fire-fighting planes and one helicopter were battling the blaze from the air, assisted on the ground by a team of 20 firefighters with 10 fire engines and a 15-strong team on foot.
