PARIS — The sound of sirens, angry chants and the crack of stun grenades echoed throughout the French capital Saturday as Parisians braced themselves for what many feared would be the most violent protests in weeks of forceful anti-government demonstrations that have swept the country.

Protests that began last month against planned tax hikes on gas have since morphed into a wider rebuke of Emmanuel Macron’s presidency and an expression of anger at his attempts to reform France's long-ailing economy.

Almost eight in 10 people in France support the protests, according to a poll published last week.

Paris was largely deserted on Saturday morning, apart from the thousands of protesters in their now-famous yellow jackets who descended onto the Champs-Elysées — the scene of last week’s clashes with police — with many calling for Macron to resign.

Hundreds of people were in custody, authorities said.

As Parisians prepared for what looked to be another weekend of destruction, officials said they planned to deploy 8,000 police across the capital.

Paris’ glittering museums and galleries — including the Louvre and the Eiffel Tower — said they would not open their doors to the usual troop of holiday season tourists.

Soccer matches were also called off across the country.

The effects of the protest were felt beyond the country's borders as well, with protesters donning yellow jackets as a symbol of resistance in Belgium Saturday and Iraq earlier this week.

Protesters who spoke to NBC News on the Champs-Elysées Saturday said they were not there for violence but to send Macron a message.

"He is amplifying a phenomenon that has existed for years now," said Julian Alla, 31, a teacher from the rural Lozère region in the south of France. "That is that inequality is increasing, the rich are more and more rich and the poor are getting poorer."

"We're fed up and it makes me happy to see that everyone is here to say 'enough is enough,'" said Alla, who had travelled more than 385 miles to Paris to protest.

Antonie Gauthier, 47, who had come to the protest with his 17-year-old son said that while he himself was not struggling financially he wanted to show his solidarity with those who are.

"It's fraternity," he said, "we understand that we need taxes but we can't be taxed to the point that we can't live."

Gauthier said that many people after paying the rent and paying their taxes found themselves with nothing. "It's those people who we need to help," he said.

John Schiltz, 36, a train-track worker from the Seine et Marne region to the east of Paris, said he would continue to protest until Macron resigned.

"He has to go," he said. "He's adding all these taxes without helping us at all — it's just tax, tax, tax."

Alexandre Bouchard who had travelled up from the rural Corrèze department in central France said he had come because he wanted to protest against increasing inequality.

"There is no longer a redistribution of wealth in France," the electrician, 28, said.

Schiltz complained that the riot police had fired tear gas and stun grenades at protesters when they had no protection.

"The police's response has been too violent," he said.

In Washington President Donald Trump, who enjoyed an erstwhile bromance with the French leader, tweeted in apparent support of the protests.

There was no evidence of the so-called Yellow Jacket protesters chanting "We want Trump"

The French have a history of fiercely opposing reform and quickly falling out of love with their presidents.

Macron, a former investment banker who swept to power on a reformist agenda, was supposed to be different.

The young centrist pledged to overhaul the country's generous welfare state, which redistributes wealth across society with high taxes for the rich.

France has high levels of social security and workers' rights, making it difficult to enact business-friendly reforms in spite of persistent unemployment.

But while he's enjoyed a high profile on the global stage, he has struggled to pass legislation at the heart of his domestic agenda.

Bouchard, from Corrèze, said he was concerned that Macron would break up the welfare state by liberalizing key services.

"We want to defend the French social model, especially anything to do with education or health," he said.

Macron has faced demonstrations throughout his year-long tenure, but the "Yellow Jacket" protests represent a more fundamental challenge to his authority.

A November poll found that only 26 percent of French people have a favorable opinion of their president.

The findings mean Macron is now less popular than his predecessors Francois Hollande and Nicolas Sarkozy at the same stage of their presidencies. Both would eventually leave office beset by opposition and scandal.

The protests gained even more momentum this week after French farmers and trade unions vowed to join the fray.

Students have also been protesting across France in a series of demonstrations against education reform, some have said they are protesting in solidarity with the "Yellow Jackets."

As different grievances on the palette of discontent begin to merge, many people in Paris said they thought it would become increasingly difficult for Macron to put an end to the unrest.

In a last-ditch attempt to quell the uproar, Macron agreed Wednesday to abandon the gas tax increases which he had previously defended as necessary to help reduce France’s dependence on fossil fuels.

However, his concessions appear to have fallen on deaf ears.

Many on the streets of Paris Friday accused Macron of not listening to the people and several said his U-turn amounted to too little too late.

“The government should do more, it should have reacted better,” said Abdul Asis, a 28-year-old construction worker who described himself as “100 percent behind the Yellow Jackets.”

Joseph Downing, an expert in French politics at the London School of Economics, agreed that the protests were about "much more" than taxes on gas.

“It’s this entire idea of the squeezed middle or the squeezed upper working-class person who feels an entitlement to an ever-increasing standard of living but is something that no politician can deliver,” he said.

“This is where we’ve seen disenfranchisement with Sarkozy, with Hollande and now with Macron.”

The self-organized approach of the protest, which sprung up from the depths of social media, is also a relatively new phenomenon in France where people have historically relied on the powerful unions to organize discontent.

Several people who spoke to NBC News before the protests Saturday said the strength of the "Yellow Jackets" lies in the fact that the protest isn’t specifically linked to any political party or union and has therefore united swathes of the population.

“The politicians are afraid because they don’t know how to stop it,” said Julian Guillo, a 23-year-old property student. “It’s not one organization, it’s the people.”

Several people directed their frustration directly at Macron, who they described as out of touch.

“He’s the president of the rich,” said Louis Boyard, a student leader at the high-school student protest Friday. “The youth are angry, we are against Emmanuel Macron."

Among the many grievances listed at the protest were changes in university admissions procedures and fees, which students and teachers said would make admission more selective and limit access to higher education.

“We have to get rid of Macron to get to a fairer society,” said Homa Javadi, 18, who said she supported the cause of the so-called Yellow Jackets.

But while the anger is widespread, the appetite for violence and destruction is not.

“Vandalizing the Arc de Triomphe is unacceptable,” said Lea Chauvet, a high school graduate who was chatting with a friend outside the Pantheon, a mausoleum to the distinguished citizens of the republic, on Friday.

"I wouldn't want to associate myself with people who destroy everything," she added, explaining one reason she would not go to the protest.

It’s not just the students who lay the blame at Macron's door, though. André Rubinot, a retired baker whose old boulangerie stands in the shadow of the Eiffel Tower, said the president talked down to the people and portrayed himself as “king-like."

The fact that Macron has largely kept a low-profile since surveying the damage after last weekend's protests has further angered those looking for signs of change from the presidential palace.

“He’s not saying anything and the country’s on fire,” said Meredith Saban, 38, a director of a human resources firm said who was having a cigarette on the Champs-Elysée.

"He’s mocking the people."
