On a 5.5 kilometre trek from Montparnasse to Place de la République in the heart of Paris, demonstrators in colourful ensembles doused themselves with water as the French capital suffered one of the worst heatwaves the city has ever experienced. "I think it's the hottest day of the week so far.
May be even ofthe whole summer. But it's worth it. It's not a problem. I've got three-and-half litres of water in my bag that I can share,” said a demonstrator.
