Police in riot gear are seen pushing back and tackling crowds of young people to the ground in Strasbourg, after protestors charged towards police with dustbins and smoke flares.

Riot police use water cannons against protestors in Rennes, western France.

Protestors and police are in the middle of an “extremely tense standoff” in the streets of Lyon, a French journalist has reported.

Julien Damboise posted a video on social media which shows fires ablaze on the streets, as protestors throw multiple projectiles and mortars towards the police.

Riot police are responding by using tear gas on the crowds, he reported.

He wrote: “An extremely tense standoff is unfolding in the streets near where the procession is set to arrive.

“Barricades are ablaze, and local construction sites are providing rioters with an endless supply of projectiles. Police are responding with tear gas.”

Distance learning programs set up in closed high schools due to protests are now experiencing disruptions due to “cyber blockades”.

Young activists have been sharing tips on social media explaining how to disrupt virtual lessons, protest monitor Contre Attack reported.

One video which has been viewed hundreds of thousands of times, shows a high school student explaining the concept of an “e-blockade” and why it will be effective.

Protesting pupils blockaded their high schools again Tuesday, a day of planned demonstrations that will test the resilience and energy of a weeks-old nationwide movement demanding more resources for the school system.

At the Hélène Boucher lycée, or high school, in Paris' 20th district, protesters laid trash cans and bicycles on their sides to create a makeshift barricade in front of the school.

Like hundreds of others around the country, the school was closed.

Authorities began shutting schools last week to take some steam out of the demonstrations after widespread damage to schools and mounting injuries among staff, students and police.

French media also reported protests in other cities and towns on Tuesday morning, as labor unions called for workers to demonstrate later Tuesday in support of the high school movement that is rattling the government of President Emmanuel Macron.

Protestors and French police have clashed in Strasbourg this morning.

France's Justice Ministry said 5,060 people have been arrested since the protests ‌began, with 87 per cent of them minors.

More than 1,800 people are being prosecuted, including 1,483 ​minors, the ministry said, without specifying the crimes. It said 790 cases had been dismissed.

At least 715 police officers and 215 teenagers have been injured in clashes, according to Lecornu's office.

Six months before an election to replace Macron, his government and the ⁠far-right National Rally, led by presidential frontrunner Marine Le Pen, have accused hard-left France Unbowed (LFI) lawmakers and mayors of stoking the protests. ‌The LFI denies the accusation.
