School protests spread in France as fires break out and teachers injured - ABC News & Headlines – Australian Broadcasting Corporation

School protests have spread across France with teachers assaulted and fires breaking out.

Students have been demonstrating against overcrowded classrooms, teacher shortages and crumbling buildings.

More than 160 schools were shut down, and university students joined the protests in Paris, Marseille and other cities.

French students have set fire to bins and erected blockades outside schools in several cities, protesting overcrowded classrooms, teacher shortages and crumbling facilities.

Several school principals were injured, harassed or assaulted during blockades at high schools on Thursday, local time, according to reports from regional education authorities, prefectures and union representatives.

Police have already detained hundreds of protesters at the lycees, which students aged 15 to 18 attend for their final three years of secondary education in France.

The interior ministry said police and gendarmes had made 1,949 arrests on Thursday, while 305 officers had been injured. Interior Minister Laurent Nunez condemned what he described as "unbridled violence".

The government said the demonstrations had become "urban violence" and cited the intelligence service to justify claims that it had been organised by the radical left.

Manuel Bompard, a leading figure in the hard-left France Unbowed party (LFI), quickly dismissed the claim, accusing the government of "sinking into conspiratorial thinking".

This latest wave of social unrest comes with tensions already running high over inflation, particularly soaring fuel prices, and just seven months away from France's presidential election where opinion polls suggest far-right leader Marine Le Pen is the frontrunner.

A security source said there had been 900 blockades or related incidents across the country on Thursday, local time.

More than 160 schools were shut down, and university students joined the protests in Paris, Marseille and other cities.

And the authorities in the Paris region said around 50 schools had been "the scene of violence, clashes and damage".

Since last week, pupils have staged protests outside schools over a range of grievances. They range from timetables, class sizes and a shortage of teachers to overheated classrooms during this year's heatwaves.

The protests have spread across the country from the Paris suburbs.

Riot police have lined up against the students, and the force has launched internal probes after accusations of brutality against three pupils, said Interior Minister Laurent Nunez.

University students also joined in Thursday, blocking access to around 30 campuses, a student union said.

Among reports of school staff being targeted was one incident in the southern port city of Marseille when a school principal and his deputy were splashed with petrol.

In the north-western city of Nantes firefighters had to intervene to extinguish a fire in the entrance of a high school "following a gathering marked by violence towards staff", the regional education board said.

Authorities reported violence near high schools, mainly in Nantes, blaming "violent individuals" who "join the students to carry out acts of vandalism".

In the north-eastern city of Strasbourg, trams were ordered to halt to "restrict the movements of rioters and demonstrators", the regional prefect said.

Raphael, a 17-year-old who did not give his surname for fear of reprisals, was among the protesters outside a school in Strasbourg, where some used barriers to obstruct the nearby tramway tracks.

"There are 35 of us per classroom. With 35 [degrees Celsius] in summer it's unbearable. There aren't enough toilets and there are water leaks in some rooms," Raphael said.

Nearby, students took photos of themselves in front of burning rubbish bins, holding up the sign with their school's name ripped off the tram stop.

Most pupils did not take part in any vandalism, instead breaking into a sprint down an avenue when the police fired tear gas.

In the southern city of Toulouse, hundreds of young people flooded the tram tracks, some toppling trash cans and starting fires, hurling projectiles or smashing bus shelters, AFP journalists said.

In the northern city of Lille, AFP reporters saw young people wearing black hoodies destroy the glass of a bus stop. Firefighters intervened to put out the flames on upturned dustbins set on fire.

The government has accused the hard-left France Unbowed (LFI) party of encouraging the protests.

But LFI's candidate for the 2027 presidential election, Jean-Luc Melenchon, said on Wednesday that his party "called for non-violent methods of struggle".

In neighbouring Belgium, there were protests and damage at a handful of schools in the eastern city of Liege, police said.
