A little earlier, killed teenager Nahel's lawyer spoke to the BBC World Service's Newshour programme.

As we've been reporting, the police officer who shot and killed Nahel has now been charged with voluntary homicide. Nahel's lawyer, Yassine Bouzrou, said the impunity police officers have in France is part of the problem.

Bouzrou said the judicial system, rather than racism, was to blame for what happened to the 17-year-old.

"We have a law and judicial system that protects police officers and it creates a culture of impunity in France," she told Newshour, adding that similar cases over the years show that "the judicial system still isn't working for victims" across the country.

With authorities anticipating another night of violence, it's just been announced that there'll be curfews in some areas of Paris - on top of the closure of tram and bus services.

One will be enforced in the suburb of Clamart, south-west of Paris, between 21:00 local time (19:00 GMT) and 06:00, from tonight until Monday 3 July.

"Clamart is a safe and quiet town and we are determined to keep it that way," a message on the town's website reads.

Meanwhile, the city of Lille will follow Paris in suspending some public transport tonight. Trams and buses will stop operating from 20:00, a statement by Lille's authorities says.

Amina Kalache, a local journalist based in Nanterre, has been talking to our colleagues over on Radio 4's World at One programme - describing how she saw a school burn last night and watched as police and firefighters tried to tackle the blaze.

"People are waiting for the truth and also for justice," she says, adding: "They don't know how to act. That's why the only answer is violence. I am not saying it is the right way - but for them, right now, it is the only answer."

Amina adds that her brother was friends with Nahel and describes him as someone who was not violent, but a "nice" and "very joyful" teenager.

"Police are meant to protect us," Amina tells the programme. "Not kill us."

The police officer who shot and killed 17-year-old Nahel has been charged with voluntary homicide and placed under arrest.

It comes after the local prosecutor of Nanterre, where the teen lived and died, said earlier that the officer involved had been put under formal investigation for voluntary homicide.

An only child brought up by his mother, Nahel, the teenager shot dead by police, had been working as a pizza delivery man and played rugby league.

His education was described as chaotic. He was enrolled at a college in Suresnes not far from where he lived, to train to be an electrician. His record of attendance of college was poor. He did not have a criminal record but he was known to police.

Those who knew him said he was well-loved in Nanterre where he lived with his mother Mounia and had apparently never known his father.

Shortly after 09:00 local time on Tuesday, he was fatally shot in the chest, point-blank, at the wheel of a Mercedes car for driving off during a police traffic check.

"What am I going to do now?" asked his mother. "I devoted everything to him," she said. "I've only got one, I haven't got 10 [children]. He was my life, my best friend."

We're continuing to listen across French media, with outlets now reporting that three special and elite police units are on standby.

They're ready to intervene should tonight's predicted protests get out of hand, reporters say.

Earlier Gerald Darmanin, France's minister of the interior, said 40,000 police officers would be deployed across France tonight.

As we reported earlier, French police have clashed with protesters following a march in tribute to 17-year-old Nahel M.

More than 6,000 people had attended the vigil, along with his mother, in the town of Nanterre to the west of Paris where he grew up.

Pictures now emerging show burning, overturned vehicles in the street and people running from tear gas. Another picture shows a protester hurling a rock, while footage appears to show police officers injured.

French media reported earlier that some people who had wanted to attend the march were fearful of more violence breaking out. One woman told the BBC she went because the incident made her question how much she could trust the authorities.

As officials brace themselves for what could be a third night of unrest, French broadcaster BFMTV reports that buses and trams are to be suspended in the Paris region from 21:00 local time (19:00 GMT).

It follows a request by the president of the Île-de-France region, Valerie Pecresse, the channel says.

Pecresse herself has spoken on the matter, saying the decision was taken to "protect agents and public transport users". She added: "Our transport network won't be a target for thugs and hooligans!"

In the last few minutes we've been hearing a little more from French Prime Minister Elisabeth Borne, after she spoke to reporters earlier.

Addressing the latest unrest, between march attendees and the police, she again called for calm and told rioters: "Destroying your own neighbourhood... won't solve anything. The investigation is ongoing... let's allow it to continue peacefully."

During a meeting with other members of the government, Borne told reporters she wanted to extend her "support and that of the government to the cities facing unrest... and to police forces who are working to preserve order".

If we hear any more from her, or President Emmanuel Macron, we'll let you know.

Some 6,200 people are now thought to be at the march in Nanterre, according to a police source who spoke to the AFP news agency on the condition of anonymity.

Earlier it was estimated that hundreds, possibly thousands, were there - but this seems to be the first reported figure.

The BBC hasn't been able to independently verify this number.

We're seeing the first signs of clashes between police and those attending a march in Nanterre, led by the mother of Nahel who was shot dead by an officer on Tuesday.

Police were captured using tear gas as some protesters attempted to kick the canisters back at officers on the sidelines of the march.

We have another voice to share with you now - that of another worried mother. Oleia, 32, has been speaking to Le Monde newspaper from Fresnes, Val-de-Marne - another suburb of Paris, about an hour from Nanterre where Nahel was shot.

She says it is "always the same story" with incidents like this - and the same types of children being targeted.

"The system is racist," Oleia says, telling the paper that as the parent of a black child, she knows "he can be perceived as an aggressor". She says she has to teach her son to be "docile" to ensure he doesn't face any problems.

"We know it's a risk for our children to be outside in public spaces," Oleia adds.

Huge crowds, now estimated to be in the thousands, have turned up to march and show their support to Nahel's relatives after his death.

Evane, 22, is among them. He tells me:

Sabrina, who has two sons and lives in a nearby neighbourhood, also speaks to me. She says:

You can now watch the march, being held in memory of Nahel, right here.

Just before the march began, Nahel's mother Mounia gave an interview to French media outlet Blast in which she remembered her son as "a respectful, kind boy".

She said that before heading out on the morning he was killed, "he told me 'Mum, I love you'... I left for work, and unfortunately an hour later I got the call saying that my son had been shot".

"My life, my heart was taken away from me. I miss him. It's so painful," Mounia continued.

She asked "everyone" to join the march currently taking place in Nanterre, saying the route is one Nahel used to take on his motorbike. "It was a route he loved," his mother said.

We're seeing more pictures now from Nanterre, the suburb of Paris where Nahel M was shot dead by a police officer.

Hundreds of people have gathered to demand justice for the 17-year-old.

Most are chanting "Justice pour Nahel" as they begin walking through the streets. Here's a look at the scene.

French TV are carrying images of the march underway in Nanterre. It's hard to tell how many people are in attendance, but local media estimate it is at least a few hundred.

Many are wearing white T-shirts emblazoned with "Justice for Nahel", as we've said, and several are carrying signs with anti-police slogans.

People seem to be chanting the phrase, too.

Nahel's mother is at the front of the crowd. She is joined by the sister of Adama Traoré, a young black man who died in custody after being restrained by police in 2016.

The march we've been reporting on, organised in memory of 17-year-old Nahel M, who was killed by French police at a traffic stop, has begun.

We're keeping across French media and social media, and can see that Mounia - Nahels' mother who organised the march - is leading a sizeable crowd filled with people wearing white T-shirts that say: "Justice Pour Nahel [Justice for Nahel]".

Mounia has said she hopes the tribute will be an opportunity for the community in and around Paris to remember her son.

Donald Culbertson, a 64-year-old American from Texas, has been living in Nanterre for two years.

He took his dog for a walk last night and "heard explosions, smelled smoke, watched crowds of people running back and forth". He tells me they were setting up fireworks, dragging metal material on roads and setting cars on fire.

Reacting to teenager Nahel M's death, Culbertson says: "In the US we're comfortable with [used to] policemen shooting people in the face at traffic stops. It’s a new thing here, it’s horrible."

He goes on to explain that what Americans have learnt to tolerate is "just now happening here and people are not tolerating it". "I look at it much as the Black Lives Matter movement, and I think it’s important and relevant that it exists and that reactions occur," he adds.

Culbertson also says he'll be at the march organised by Nahel’s mother, which is thought to have begun in the last few minutes.
