Eight people have died in recent days following the wildfires in Mediterranean countries.
Tens of thousands of hectares of countryside have been devastated mainly in Italy, Spain, France and Greece.
New fires began in some of the worst hit areas, but also in Croatia, with the latest again blamed on arson.
The continued threat posed by weather conditions was underlined near the Spanish town of Las Hurdes where a blaze that appeared to have been brought under control flared up overnight due to strong winds, forcing the evacuation of over 500 people.
More than 400 firefighters were battling the blaze, which has so far ravaged some 500 hectares.

In neighbouring Portugal, which has suffered no major forest fires in recent days, its weather office put six districts in the centre and south of the country on 'maximum' alert for wildfires because of hot, tinder-dry conditions.

French firefighters have been battling a blaze which has raged since Thursday near Aullene on the Mediterranean island of Corsica, which has destroyed 3,500 hectares of forest and bush.
