A severe and sustained heatwave across Europe has triggered widespread deaths, shattered temperature records, and disrupted transport, work, and public services, with France emerging as the hardest hit as authorities warn the crisis is far from over.

French officials on Tuesday said at least 40 people have died in recent days during an intense spike in heat, with many of the fatalities linked to drowning as residents attempted to cool off in rivers, canals, and lakes.

Prime Minister Sebastien Lecornu described the situation as a “sad scourge,” noting that most of the victims were young people.

Among the most distressing cases, prosecutors in Carpentras said two children, ages 2 and 4, were found unconscious inside a parked car outside their home in southeastern France. Emergency responders were unable to revive them.
