More than 1,000 firefighters are fighting a “monster” fire in southwestern France that has already destroyed nearly 7000 hectares of forest, officials say.
The raging fire near the city of Bordeaux destroyed several houses and forced 10,000 residents to flee.
Strong winds and high temperatures hinder fire extinguishing activities.
President Emmanuel Macron announced that Austria, Germany, Greece, Poland and Romania “come to help France” to fight the fire. “European solidarity at work!” he tweeted.
This summer, France and a number of other European countries have experienced a wave of deadly wildfires triggered by record temperatures and droughts across the continent.
More than 1,000 deaths have been attributed to heat in Portugal and Spain.
A yellow extreme heat warning has now come into effect in the UK, with temperatures expected to reach 37C (99F) in some areas over the next four days.
The heat wave is likely to have an impact on health, transport and working conditions, warn the authorities. Forest fires are rampant in Greece, Spain and Italy as the heat wave moves across Europe
The massive forest fire in the French Gironde has been raging for two days near the municipality of Landiras, about 30 km south-east of Bordeaux.
A number of firefighters had to be relocated urgently from other regions to boost the ongoing operation.
They are supported by specialized aircraft that have released water and flame retardants.
But despite all efforts, the fire was still not under control on Thursday, local officials said.
Before the evacuation, some of the local residents had to save themselves on rooftops as the flames rapidly approached their houses, reports say.
Belin-Béliet is now a ghost town since all of its 2,000 inhabitants had to flee on Wednesday.
In nearby Hostens, Allisson Fayol and her father – unlike many of their neighbours – decided to stay at home for now.
Temperatures are expected to reach as high as 39C later on Thursday. Prime Minister Elisabeth Borne and Interior Minister Gérald Dermanin arrived in the affected area to inspect the scope of the damage.
Climate change increase the risk of the warm and dry climate that will probably feed forest fires.
The world has already been heated about 1.2 ° C from the beginning of the industrial era and temperatures will continue to climb unless governments of the world do not make steep cuts on emissions.
