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.

Southern Europe is experiencing one of its worst wildfire seasons in two decades, with Spain among the hardest-hit countries.

Two firefighters have been killed in Spain and Portugal, the authorities said on Monday, as wildfires ravage the Iberian Peninsula during a sweltering heatwave.
