Firefighters in Greece were battling flames for a ninth consecutive day on Sunday, as more areas of the country's north were ordered to evacuate their homes.
The largest fire is devastating the region of Evros, near the port town of Alexandroupoli and the country's border wth Turkey.
On Sunday, residents of the areas of Lefkimmi in Evros and Kassitera, in the neighbouring region of Rhodopes, were ordered to evacuate their homes.
The deputy regional governor of Evros, Dimitris Petrovic, told public television channl ERT that it was a "very difficult situation" that had caused enormous damage.
The region had launched a new appeal for reinforcements and resources, he said, adding that the winds were set to change from Monday.
"We don't know how and if we will be able to stop the advance of the fire's frontline," he said.
Since the fire started last Saturday 20 people believed to be migrants, including two children, have been found dead in the area.
The Evros region is a regular entry point for migrants from neighbouring Turkey, and local border guards had warned that more asylum-seekers could have been trapped by the fires.

The fire was also consuming the Dadia forest, one of the major sanctuaries in Europe for birds of prey.
The Alexandroupoli wildfires are now the largest in the EU on record for 2023 and the second largest since 2000, according to the bloc.
Another dangerous fire continues to destroy vegetation on Mount Parnitha, near Athens.
