Four people died in Spain, two in France and two in Italy as an early summer heatwave continued to grip much of Europe on Wednesday, triggering health alerts and forest fires and forcing the closure of a nuclear reactor at a Swiss power plant.
Spanish officials said a wildfire in Catalonia had killed two people a day earlier, and authorities reported heatwave-linked deaths also in Extremadura and Cordoba. France's energy minister reported two deaths linked to the heat, with 300 others taken to hospital.
