The fires in Spain this year have burned 158,000 hectares or 610 square miles, according to the European Union’s European Forest Fire Information System. That is an area roughly as big as metropolitan London.

Spain on Friday warned of "very high or extreme fire danger in most of the country," as firefighters there continue battling 14 blazes in temperatures up to 104 degrees Fahrenheit.

Portugal suffered its first death Friday from the fires raging there, as Spain's weather agency warned of a "very high to extreme risk" of more wildfires there during Europe's intense heatwave. Further east, Greece was still fighting blazes on one Aegean island, but the situation had improved for several other southern European countries.
