Hundreds more people were evacuated from their homes as wildfires blistered land in France, Spain and Portugal on Friday, and officials in Europe issued health warnings for the heatwave in coming days. More than 1,000 firefighters, supported by water-bomber aircraft, have battled since Tuesday to control two blazes in southwestern France that have been fanned by scorching heat, tinder-box conditions and strong winds. While temperatures dipped a little in Portugal, they were still expected to top 40 degrees Celsius (104 Fahrenheit) in some places, with five districts on red alert for extreme weather and more than 1,000 firefighters tackling 13 wildfires, authorities said.
