A deliberate fire tore through the entrance hall of Lycée Nelson-Mandela in Nantes on Thursday, October 1, as a growing wave of school blockades and student protests spread across France.
The blaze broke out during a morning blockade at the school on Île de Nantes. TF1 reported that the fire began after a rubbish bin was set alight before flames spread into the school’s entrance hall and across part of the façade.
Incident time: Around 8:00 a.m. local time (CEST)
Date: Thursday, October 1, 2026
Location: Lycée Nelson-Mandela, Île de Nantes, Nantes, France
Videos from the scene showed large flames and thick black smoke rising above the campus as firefighters moved in to contain the blaze.
By later Thursday morning, the fire had been brought under control, but the damage was significant. The entrance hall was badly damaged and flames had spread onto the exterior of the building.
What happened at Nelson-Mandela High School in Nantes
Lycée Nelson-Mandela is a public secondary school at 10 Rue Pierre Vidal Naquet on Île de Nantes.
According to TF1 Info, the first fire was reported at around 8 a.m. after flames broke out in a rubbish bin during the blockade.
The fire then spread into the entrance hall of the school and onto the façade.
Firefighters moved quickly to prevent the blaze from spreading further through the school complex, while police secured the surrounding area.
No deaths were reported in connection with the Nelson-Mandela school fire in the initial official accounts reviewed Thursday.
School administration says the fire was deliberate
The most important development came later Thursday when deputy head Gaëlle Cordier described the blaze as a deliberate fire.
Speaking to AFP, Cordier said an “incendie volontaire” had been started and had spread to the façade of the school, according to RTL.
However, authorities had not publicly identified who started the fire or established whether those responsible were students involved in the blockade, other protesters or people outside the student movement.
That distinction remains important because competing claims emerged almost immediately after the fire.
Christelle Morançais, president of the Pays de la Loire region, condemned the violence and destruction around the protests.
Local MP Andy Kerbrat said people outside the high-school protest movement were responsible for starting the blaze. That claim had not been independently established by investigators at the time of publication.
The confirmed point is that the school’s administration considers the fire deliberate, while responsibility for starting it has not yet been publicly determined.
Nelson-Mandela school expected to remain closed for weeks
The damage is serious enough that Lycée Nelson-Mandela is expected to remain closed for several weeks, according to RTL.
That creates an immediate challenge for students and families, with school officials now needing to determine how lessons will continue while parts of the building remain unusable.
The entrance hall sustained the heaviest reported damage, but a full assessment of classrooms, boarding areas and other parts of the campus had not yet been publicly released.

France school protests spread nationwide
The Nantes fire unfolded against a rapidly expanding protest movement over conditions in French schools.
Students have protested over issues including absent teachers not being replaced, overcrowded classes, deteriorating school buildings and broader concerns about education resources and learning conditions.
According to Euronews, 356 schools were affected by protests and blockades on Wednesday.
Interior Minister Laurent Nuñez said 625 people were detained on Wednesday, while 83 police officers and gendarmes were injured.
Education Minister Édouard Geffray said 119 students and education staff had been injured since the unrest began, including 34 education workers.
Thursday brings another wave of arrests and clashes
The movement continued into Thursday rather than fading after Wednesday’s large demonstrations.
By around 11 a.m., TF1-LCI reported 500 arrests and 50 injured police officers across France outside Paris and its inner suburbs.
Those figures refer to Thursday’s developing situation and should not simply be added to Wednesday’s numbers because the reporting periods and geographic coverage differ.
Actions were reported in Nantes, Paris, Lille and several other cities as the movement widened.
University students join the movement
Thursday also marked an expansion of the unrest beyond secondary schools.
University students joined demonstrations and blockades in several parts of France, with campuses in multiple cities affected.
The spread into universities increased pressure on the French government as officials tried to contain violence while responding to complaints about staffing, school facilities and education conditions.
Government responds as protests escalate
Prime Minister Sébastien Lecornu convened an interministerial crisis meeting on Thursday as the protests widened.
The government has condemned arson, attacks on public property and violence around some blockades while separately acknowledging concerns raised by students over staffing shortages and school conditions.
The protests initially gained momentum around the Paris region before spreading to cities including Lille, Lyon, Strasbourg, Nice, Marseille and Nantes.
Many demonstrations have focused on education demands, but some protest sites have also seen burning bins, barricades, projectiles and clashes with police.
Serious incidents also reported in Marseille
The violence surrounding some of Thursday’s school protests was not limited to Nantes.
In Marseille, serious incidents were reported at schools affected by the unrest, including an attack in which a headteacher was reportedly doused with petrol.
A fire engine responding to another school-related blaze was also attacked and set alight after firefighters were forced away from the vehicle.
The incidents underline the increasingly complicated situation facing authorities: a broad student movement over school conditions is continuing across France, while separate acts of violence and arson have occurred around some protest locations.
What remains unknown about the Nantes fire
Several important questions remain unanswered despite confirmation from the school administration that the Nelson-Mandela fire was deliberately started.
Authorities have not publicly named a suspect, confirmed how many people were involved or established whether the person responsible was part of the student blockade.
Investigators will also need to determine whether the initial rubbish-bin fire was intended to damage the school building itself or whether the blaze spread beyond what those responsible intended.
For now, the strongest confirmed details are that the fire broke out at around 8 a.m. during Thursday morning’s blockade, spread into the entrance hall and façade, was described as deliberate by the school administration and is expected to keep Lycée Nelson-Mandela closed for several weeks.
