Firefighters in Spain, Portugal and Greece battled ongoing wildfires Friday, an important religious holiday in all three countries, as persistent hot, dry conditions challenged efforts to contain the blazes.

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.
