A severe heat wave is gripping Europe, setting a national temperature record in Austria, fueling wildfires in France and Greece, and disrupting energy and transportation systems across the continent.
In Italy, all but two of the country's 27 major cities are on red alert for extreme heat, and the intense conditions are not forecast to let up for at least a week.
The heat has also exposed Nazi-era shipwrecks from the Danube as water levels drop, and raised concerns about cooling risks at nuclear reactors.
Greece is battling deadly wildfires, while France has seen blazes fueled by the heat.
Authorities across the region are urging caution as the prolonged hot spell continues to strain infrastructure and emergency services.
