Thousands of firefighters were having trouble containing forest fires in France, Spain and Portugal that have destroyed thousands of acres of land. The fires have forced thousands of people to evacuate to safety, as extreme heat grips the region.

Wildfires are happening earlier in the season, ending later and becoming more frequent because of climate change, the European Union said in a report last year.
"Climate change is aggravating the situation, making countries more prone to wildfires and increasing the intensity of such events," the report said.
The sweltering heat is also expected to take hold of other parts of Europe in the coming days. Areas of England are expected to hit 40 C (104 F) on Tuesday.
The U.K. government issued a national emergency and warned people not to leave their homes unless necessary, according to The Associated Press.
