Raging forest fires in Portugal have killed at least 62 people, most of whom burnt to death in their cars, the government said Sunday, in one of the worst such disasters in recent history.
Avelar resident Isabel Brandao has told The Associated Press that "the problem is that there was no rain". Police say lightning striking a tree may have caused the fire. But Prime Minister Antonio Costa said high temperatures of 40 C (104 F) in recent days may have played a part.
The forest fire deaths were the biggest in memory in Portugal, which saw 25 Portuguese soldiers die fighting wildfires in 1966.
Six firefighters are among those injured. The rest of the bodies were found outside of the cars or in the forest, the official said.
