The remains of eighteen people believed to be migrants, were found in a forested area of northern Greece on Tuesday.
Wildfires have raged for four straight days across the region and had already claimed the life of an undocumented migrant in the Dadia national park on Monday.
An elderly shepherd had also been found dead in the Boeotia region earlier Monday.
Dadia is one of the most important protected areas in Europe, offering an ideal habitat for rare birds and also home to the only breeding population of black vultures in the western Balkans.
It comes as patients at Alexandroupolis General Hospital were evacuated late on Monday night due to a large fire approaching the northeastern Greek city.

Two separate alert text messages were issued for residents, alerting them to heavy smoke and ordering them to stay indoors, shutting all doors and windows.

The European Union announced it was deploying two Cyprus-based firefighting aircraft and a Romanian firefighting team via the bloc’s civil protection mechanism.
The very hot and dry conditions that increase the fire risk will persist until Friday, according to meteorologists.
Amid a heatwave, a fire that started on July 18 and was fanned by strong winds ravaged almost 17,770 hectares in 10 days in the south of Rhodes, a popular tourist island in the southeastern Aegean Sea.
Around 20,000 people, mostly tourists, had to be evacuated.
