A three-year-old has been found dead in a car in the Paris region, a police source said on Thursday, the third such fatality of a child during the extreme weather this week.
Parents found the boy in "the car outside their home", the source said, while civil defence confirmed his death in the town of Saint-Gratien in the Paris suburbs.
It comes just days after siblings aged two and four were found dead in a car in Carpentras in south-east France.
Although the investigation is ongoing in that case, police say that they believe the children wandered off during a family visit and got into the car, then becoming trapped.
France has been scorching under an extremely intense and long-lasting heatwave for the past week.
