French police have fired tear gas at protesters at a large demonstration in the west of the country.
Thousands of people had gathered in Sainte-Soline to protest against plans for a new water reservoir.
Several police cars were set on fire after clashes broke out at the construction site.
The unrest follows weeks of anti-government demonstrations in Paris and other cities over President Emmanuel Macron’s pension reforms.
Though unrelated to the protests on pension reforms, the latest demo adds to the growing sense of public anger within France.
The procession set off late morning despite a police ban, with at least 6,000 people taking part, according to local authorities.
