In Cantabria, local officials said 99 percent of the fires have been started deliberately. Some 400 firefighters and soldiers were working to contain 82 wildfires that have been burning in the region over the past week.
In the regions of Asturias and Basque Country, wildfires are being fueled by high winds of up to 110 kilometers (70 miles) an hour.
Two fires were also said to be raging in the northeastern region of Navarra, located along the border with France.
Cantabria’s regional government said at least 2,000 hectares (5,000 acres) of land of “extraordinary ecological value,” including two natural parks, has been destroyed.
