Alwaght- French Police fired tear gas at "yellow vest" demonstrators who were marching across the country for the 21st consecutive week on Saturday.
There were 28 arrests in Paris and some clashes with police in Rouen. The French authorities had issued protest bans for the Champs-Elysees and areas near the Elysee Palace and the National Assembly in Paris.
The protests, named after the high-visibility safety jackets worn by demonstrators, started last November as an expression of public anger against fuel tax increases.
The movement soon morphed into a broader backlash against President Emmanuel Macron's government, despite a swift reversal of the tax increases and other hurried measures worth more than 10 billion euros ($11.2 billion) to boost purchasing power for less affluent voters.
Despite the scuffles in Nantes, other demonstrations in major French cities remained calm on Saturday compared to recent weeks in part because of a high level of mobilization of police.
At o2 p.m. local time (1200 GMT), there were 6,300 demonstrating around France, with 3,100 marching in Paris, according to the French interior ministry.
