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.

Spain’s national weather agency warned of extreme fire risk in most of Spain, including where the largest blazes were burning in the north and west.

Spain is battling a series of devastating wildfires that have killed two people and destroyed thousands of hectares of forest and scrubland. There are currently 14 major active fires, Minister for Ecological Transition Sara Aagesen told radio station Cadena Ser on Wednesday.
