Firefighters were struggling to tame blazes in several countries in southern Europe, including Albania, Greece, Montenegro, Spain, and Turkey.

Spain's weather agency warned the public on Monday to be "cautious" of the "very high or extreme fire danger."

Spain is deploying 500 more soldiers to battle fast-spreading wildfires, as a brutal heatwave and strong winds leave nearly the entire country at extreme risk. Fires have already scorched land equal to the size of London and killed seven people.
