How fast are the Greece wildfires spreading in Avantas

Eighteen bodies have been found in a forested area of northern Greece, outside the village of Avantas, hit by wildfires for the past four days, the Greek fire service has said.

Initial reports suggest those who died may have been migrants.

Fires are raging across several fronts in the nation, whipped up by high winds and temperatures which climbed above 40C in several places on Tuesday.

The Evros region of north-eastern Greece, not far from the Turkish border, has been ravaged by fires.
