In neighbouring Portugal, where fires are also blazing, another firefighter was killed on Sunday in a "tragic" traffic accident, President Marcelo Rebelo de Sousa said. Fires have also broken out in Greece, France, Turkey and the Balkans as a heatwave has scorched swathes of southern Europe.

Wildfires have ravaged more than 450,000 hectares of land across the Iberian peninsula since the start of the year, setting records in a region particularly hard hit by intensive heatwaves and drought affecting southern Europe.

Spain tackled several major wildfires on Tuesday in one of the country's most destructive fire seasons in recent decades, despite temperatures dropping across the Iberian Peninsula.
