A protester has died and there are reports of injuries elsewhere as demonstrators angry at rising fuel prices disrupt traffic across France.
The female protester was struck after a driver panicked and drove towards demonstrators, reports said.
Some 50,000 demonstrators, dubbed the "yellow vests" after their high-visibility jackets, have gathered in 1,000 locations, officials say.
They accuse President Emmanuel Macron of abandoning "the little people", according to BBC.
Mr Macron admitted this week that he had not "really managed to reconcile the French people with their leaders".
Nonetheless, he accused his political opponents of hijacking the movement in order to block his reform programme.
Officials have warned that, while they will not stop the protests, they will not allow them to bring the French road network to a standstill.
