A British woman has died at a campsite in France, while a three-year-old boy was found dead inside a sweltering car in Paris as the country endured its hottest day on record.
The temperature climbed to 44.3C in the southwestern town of Pissos on Tuesday, marking the highest reading ever documented in France.
The elderly woman had been staying with her husband at the Baie D-Aunis campsite in the coastal town of Tranche-sur-Mer, in western France, when she became unwell.
In a separate tragedy, a three-year-old boy was discovered dead in a car in a Paris suburb as temperatures in the capital reached 41C.
A police source said the child’s parents found him in “the car outside their home” on Wednesday.
The parents had reportedly put the boy to bed after he told them he was feeling tired.
About 45 minutes later, they noticed he was not in his bedroom and later found him unresponsive inside the vehicle, according to local media reports.
Investigators believe the boy may have locked himself in the car, though it remains unclear how he came to be inside the vehicle.
