Police in Paris have used tear gas and water cannon to disperse protesters, in a second weekend of demonstrations sparked by rising fuel prices.
Violence erupted on the Champs-Elysées as protesters tried to get through a security cordon around sensitive sites.
About 5,000 protesters had converged on the avenue. Dozens of people were arrested after clashing with police.
Organisers of the “yellow vest” movement billed the latest protests as “act two” in their rolling campaign.
Named after their distinctive high-visibility attire, the protesters oppose an increase in fuel duty on diesel.
More than 100,000 took part in Saturday’s protests across the country. They passed off largely peacefully – except in the capital, where 8,000 demonstrators gathered.
