France on Monday counted its heat-related deaths, as a funeral business representative said Paris morgues have been overwhelmed by a spike in fatalities during a record-breaking heatwave.

Prime Minister Sebastien Lecornu was to chair a meeting on the impact of the heatwave, which eased on Sunday after days of punishing temperatures that disrupted daily life and forced the closure of many schools and landmark tourist attractions.

The government would prepare for future episodes of extreme heat that scientists link to climate change, Lecornu's office said.

Elisabeth Charrier, head of the National Funeral Federation, said funeral home occupancy -- which typically ranges between 30 percent and 45 percent during the summer -- has climbed above 66 percent nationwide.
