Violence broke out for the 13th week in Paris as riot police took on yellow vest protesters.
In the midst of tear gas and baton charges, one protester lost a hand in horrific circumstances.
The cause of the injury has not been confirmed but eyewitness claim he picked up a tear gas grenade that exploded in his hand.
Police say he is being treated in hospital.
Brief clashes erupted on the Champs-Elysees between protesters and law enforcement with the latter reportedly using batons and pepper spray.
The protests – which were originally against the rise in diesel costs – have turned into a general discontent against French President Emmanuel Macron and high living costs.
Various events were also planned in other cities, including Montpellier, Lille, Nantes, Rennes, Brest, Caen and Lorient.
