Tear gas and water cannons have been unleashed on protesters in Paris amid growing unrest over rising fuel prices in France.
Images show violent clashes between demonstrators and police as authorities attempted to control the situation, with thousands gathered in the French capital.
This is the second weekend of “yellow vest” protests, from those angry at the inflated fuel costs and President Emmanuel Macron’s economic plans.
Two deaths were previously linked to the unrest across France while 606 people have been injured in prior demonstrations, the Interior Ministry said on Thursday.
By 2pm GMT, more than 80,000 demonstrators were protesting across France, with 8,000 in Paris alone, according to official figures.
Police detained 22 people in Paris and at protests in other parts of the country.
There have not been reports of injuries so far this time out, despite the scenes leading to police even using rubber bullets.
At one point, a man who tried to attack fire fighters was overpowered by some of the demonstrators themselves
Barricades were used to block off roads which could be seen ablaze in the streets, while a trailer was also set alight and exploded in the French capital.
Some of those gathered sang the national anthem and others held signs aloft with slogans saying "Macron, resignation" and "Macron, thief".
Protesters clad in fluorescent yellow jackets, the sort which all motorists in France must have in their vehicles, have blocked highways across the country for more than a week.
They have done so with burning barricades and convoys of slow-moving trucks while also obstructing access to fuel depots, shopping centres and some factories.
Those demonstrating are opposed to taxes President Macron introduced last year on diesel and petrol.
Along with the taxes, the government has offered incentives to buy green or electric vehicles, as part of a strategy designed to encourage people to shift to more environmentally friendly transport.
Security forces are concerned that far-left and far-right extremists may infiltrate the demonstrations, escalating the crowd-control challenges.
Denis Jacob, secretary general of police union Alternative Police, spoke of the large figure expected in Paris and some of the concerns posed by this.
"We know there are ultra-right and ultra-left infiltrators. You can also expect gangs from the suburbs and 'black-blocks'," he said, referring to a militant protest force.
Around 3,000 police officers have been drafted in to work in Paris on Saturday, city hall said.
Security forces are also dealing with a demonstration against sexual violence, a soccer match and a rugby game on the same day.
The unrest is a dilemma for President Macron, who is fighting a slump in popularity.he leader has seemingly positioned himself as a champion against climate change but he has been derided as out of touch with the general public.
Voters appear to be growing restless with the 40-year-old president's popularity slumped at barely 20 percent.
The French leader has seen off trade union and street demonstrations against his changes to the labour rules and overhauled the heavily indebted state rail operator.
Despite issues at home, foreign investors have largely cheered his pro-business administration.
However, political foes have dismissed him as the "president of the rich" for ending a wealth tax.
In spite of the government calling for calm, the yellow vest protests have even spread to French territories abroad.
These included the Indian Ocean island of Reunion, where cars were set on fire.
