LONDON (Reuters) -Wildfires have killed two people in Spain and two others have died in France because of a heatwave that has gripped Europe and forced the closure of a nuclear reactor at a Swiss power plant.

France's ecological transition minister, Agnès Pannier-Runacher, said the two deaths in her country were a result of "heat-related illness". It comes as France registered its second-hottest June since records began in 1900. June 2025 only trails behind June 2023, when the country also experienced intense heat.

Paris was on red alert for high temperatures on Tuesday, with the top of the Eiffel Tower shut, polluting traffic banned and speed restrictions in place as a searing heatwave gripped Europe.Mediterranean countries from the Iberian peninsula through France and Italy to the Balkans and Greece have been sweltering in a heatwave for several days,
