The Pedrogao Grande forest fire spread violently, affecting several villages; the death toll could rise further.

At least 600 firefighters are trying to put out the flames.
Residents fear for their lives
Locals thought the forest fire was far and wouldn't reach them. Soon, a huge wall of thick smoke and violent red flames towered over the trees near houses in the forest region. Intense smoke reduced the visibility to just a few meters.
