Police use tear gas in Paris protest against Macron

Paris: French police have fired tear gas and water cannons to disperse demonstrators in Paris, as thousands gathered in the capital and staged road blockades across the nation to vent anger against rising fuel taxes and Emmanuel Macron's presidency.

Thousands of police were deployed nationwide to contain the demonstrations, including a tense protest at the foot of the Champs-Elysees where protesters wielded placards reading "Death to Taxes" and upturned a large vehicle.

French President Emmanuel Macron condemned the violence by protesters.

Macron said in a strongly worded tweet: "Shame on those who attacked (police). Shame on those who were violent against other citizens ... No place for this violence in the Republic."

At least 20 people were hurt in the protests, including one with more serious injuries. Dozens of people have been arrested.

"It's going to trigger a civil war and me, like most other citizens, we're all ready," said Benjamin Vrignaud, a 21-year-old protester from Chartres.

Five thousand protesters flooded the Champs-Elysees alone, with 23,000 protesters in total nationwide, according to Interior Minister Christophe Castaner.

In a week of demonstrations that has dominated national news coverage, hundreds have been injured and two people died in accidents stemming from the protests.

The unrest is proving a major challenge for embattled Macron, who's suffering in the polls and the focus of rage for the demonstrators, who accuse the pro-business centrist of indifference to the struggles of ordinary French.

Macron has insisted that the fuel tax rises are a necessary pain to reduce France's dependence on fossil fuels and fund renewable energy investments, which is a cornerstone of his reforms of the nation. He will defend fresh plans to make the "energy transition" easier on Tuesday.

On Saturday, Paris deployed some 3000 security forces, notably around tourist-frequented areas, after an unauthorised attempt last week to march on the presidential Elysee Palace.

Authorities said protesters have so far not breached a no-go zone set up by authorities around key areas including the presidential palace and the National Assembly on the Left Bank of the Seine River.

But authorities are struggling because the movement has no clear leader and has attracted a motley group of people with broadly varying demands.

A man caused a dramatic standoff with police on Friday when he donned a neon vest and brandished an apparent grenade at a supermarket in the western city of Angers. He was later arrested.
