A deadly European heatwave is overwhelming hospitals and public services. At least 101 million people have endured temperatures above 35°C, with several hundred deaths reported.

In France, emergency room visits for heat-related illness have quadrupled. Paris police chief Patrice Faure warns hospitals are reaching a saturation point. The French capital has banned evening alcohol sales to manage the crisis.

The UK's London Ambulance Service recorded its highest number of life-threatening emergency calls in a single day. Multiple NHS hospitals declared critical incidents after cooling failures disrupted medical equipment.

The heatwave is now moving east toward Germany and Poland. Scientists from World Weather Attribution state human-caused climate change is unequivocally responsible for the record-breaking intensity.

The UN's climate chief Simon Stiell says the event has the fingerprints of the climate crisis all over it.
