A heatwave affecting much of Western Europe has resulted in several deaths, health officials say.
Temperatures are soaring in many countries
In the Netherlands, an annual walking event in the city of Nijmegen had to be called off at the half-way stage after two walkers died of heatstroke.
France's health minister linked nine recent deaths to soaring temperatures. In Paris, they hit 36C (97F).
Britain recorded its hottest day of the year so far, as temperatures hit 36.3C (97.3F) near London's Gatwick airport.
In Italy, farm union officials said the country was suffering one of the worst droughts in decades.
Heatwaves could become routine
The heatwave also forced France's energy company, EDF, to scale back electricity generation at some of its nuclear power stations. The company asked its major clients to limit their electricity use.
The punishing heat has sparked a series of health warnings.
Officials are urging people to stay in the shade and drink plenty of water.
The hot spell is being compared to a heatwave in the summer of 2003, when some 20,000 people died across Europe as a result of heatstroke and dehydration.
