Teenager's hand blown off during confrontation between France school protesters and police

A 15-year-old boy's hand was blown off during a confrontation between police and demonstrators near a school in France, an official has said, as student protests continue across the country.

The "very serious incident" happened in the northern city of Lens on Monday morning, according to the prefect of Pas-de-Calais, François-Xavier Lauch.

"The student's life is not in danger," he said, adding that the teenager was transferred "very quickly" to a hospital nearby.

Around 500 schools were partially or totally closed across the country on Monday amid student protests over the condition of school buildings and staffing which have led to clashes with police in recent days.

There are mixed reports in French media about how the boy came to sustain the injury.

The AFP news agency, citing a police union source, reported that the student appeared to have picked up a sting-ball grenade fired by riot police, which exploded in his hand.

However, regional newspaper La Voix Du Nord quoted a girl, who was reportedly standing near the teenager, as saying he did not pick up the grenade.

"He didn't pick it up. I was there, I saw it. He didn't pick it up, he didn't catch it," she was quoted as saying.

When asked about the incident, Lens Mayor Sylvain Robert said the circumstances still needed to be clarified.

"Like you, and like many others, I have seen some videos showing the aftermath. But I did not see how the operation was organised, either by the police or by the students," he told French media.

A regional prosecutor said an investigation would be carried out by the French police watchdog, the General Inspection of the National Police (IGPN), "so all light can be shed on what happened".

The incident took place close to the Auguste Béhal high school, the prefect said.

Lauch said a "larger gathering" of students than on previous days had assembled outside the school.

"At the start of the morning, they threw various projectiles at the local police officers who were on site initially. When I say projectiles, I mean stones, fireworks, and mortars," he told French media.

"Instructions were given by the interdepartmental director of the National Police, naturally with my approval, to deploy a company of riot police (CRS) here to maintain order, and it was in this context that this event occurred."

The school issued a statement on Monday morning, saying: "In light of the events that took place this morning and in order to ensure the safety of the entire school community, the institution is switching to distance learning from now on.

"In addition, to support everyone during this period, a listening and support unit has also been set up at the establishment."

According to education minister Édouard Geffray, at least 190 students have been injured since the protests began.

Last week, Eden, 14, was badly hurt in Saint-Ouen-l'Aumône after reportedly being struck in the head by a tear gas grenade.

The student suffered "a double jaw fracture" and had to undergo "extremely major surgery", according to his lawyer. Interior Minister Laurent Nuñez has announced an investigation.

Speaking at a news conference on Monday, Eden's mother said her heart was "shattered".

"His jaw is wired shut. He can't eat except through a straw and only liquids," French media outlet BFMTV reported her as saying.

"It's shameful, it's appalling, it's violent, it's horrific," she said, adding: "This should not happen. They are dealing with children who are asking for better conditions in which to study."

The recent wave of protests began in late September in Paris and has spread across the country.

High school students started the demonstrations, complaining about a lack of teachers and staff, overcrowded classrooms and run-down buildings. University students joined last week, making similar demands.

More than 5,000 people have been arrested altogether since the start of the movement, according to AFP, with around 85% of them minors.

The radical left La France Insoumise (LFI) party leader Jean-Luc Mélenchon described the protests as the "most powerful high school and university student youth movement" since 1968 - a major year of French protest, which saw millions of workers go on strike.

Education minister Geffray said Monday saw a "clear decrease" in the number of schools disrupted compared to recent days, with 589 institutions affected.

Last Friday, French authorities said 735 of France's 3,700 schools had been disrupted.

But France is braced for more large protests on Tuesday, as student organisation Union Syndicale Lycéenne (USL) has again called on people to take to the streets.

Other organisations, including the teachers' union SNES-FSU, have also shown their support for the students, urging their members to join tomorrow's protest.

In response, the French government said it would set up a "major consultation platform" for students from across the country to share details of the difficulties they have experienced.

Geffray said he hoped to resolve "most of the problematic situations" by 16 October.
