Portugal is facing a severe wildfire crisis, with more than 100 active fires and 5,000 firefighters deployed, exacerbated by recent hot weather. Seven people have died, including both civilians and firefighters, and Prime Minister Luís Montenegro declared a 'state of calamity' to mobilize additional resources. The Aveiro district is among the hardest hit, with significant property damage and evacuations. International assistance has arrived, including firefighters and aircraft from Spain, France, Italy, and Morocco. The situation is slightly improving with forecasts of cooler weather, increased humidity, and reduced wind, but multiple regions remain at high risk. Authorities are also seeking to arrest arsonists suspected of starting some of the fires.
