Outside of France, Germany has expressed "concern" about the riots gripping the country.

"Of course, we view what is happening in France at the moment with some concern," government spokesman Steffen Hebestreit is quoted as saying by the AFP news agency.

He added there was no indication yet that President Emmanuel Macron would cancel a state visit to Germany starting on Sunday.

A little earlier we showed you the video, posted here again, of a fire at the site where an aquatic training centre is being built ahead of the 2024 Paris Olympics.

It's now being reported that only the façade of the facility was damaged, according to the company in charge of the Games' infrastructures.

"Buses parked near the Aubervilliers aquatic centre construction site were set on fire," SOLIDEO told Reuters news agency.

"The façade of the building suffered very slight damage as a result."

The company didn't say whether additional security measures would be taken in the coming days.

The French president is ready to adapt security measures "without taboos", according to the Elysée palace, quoted by the AFP news agency.

PM Élisabeth Borne did not reply explicitly when asked earlier by reporters whether a state of emergency was being considered, saying only that the government was contemplating "all options" to restore security after days of unrest.

The UN’s human rights office says the current unrest in France is a chance for the country "to address deep issues of racism in law enforcement".

A UN spokeswoman in Geneva pointed to a recent report by the UN committee on the elimination of racial discrimination, which last December expressed deep concern at aspects of policing in France, including what the report suggested was the disproportionate use of identity checks and imposition of fines on specific ethnic groups.

The spokeswoman acknowledged some of the protests had turned violent, and that some police officers had been injured, but stressed that law enforcement officers must respect the principles of legality, proportionality, and accountability at all times.

More now from Borne, who said the unrest saw "very violent, very young individuals" involved in the destruction of police stations and town halls, but who were not representative of local residents who were "as shocked as we are".

The priority for President Macron was to restore order, she added.

"The priority is to ensure national unity and the way to do it is to restore order," she told reporters during her visit to the Paris suburb.

Asked by reporters if a state of emergency was being considered, she replied: "I won't tell you now, but we are looking at all options, with one priority: restoring order throughout the country."

This would be discussed at a meeting with Macron, who is returning to Paris from Brussels, at 13:00 (11:00 GMT), she added.

President Emmanuel Macron has left a European summit in Brussels early to return to France after three nights of unrest.

Macron cancelled his final press conference in the Belgian capital before making his way home where he will convene a crisis meeting with ministers today, the AFP news agency reports.

French Prime Minister Élisabeth Borne has said all options would be examined with President Emmanuel Macron to address the current unrest in France.

Borne has been visiting a police station in Evry-Courcouronnes outside Paris along with Interior Minister Darmanin to show support to the police forces who she says have been "heavily mobilised in the last hours".

French Prime Minister Élisabeth Borne is speaking to the press now as she visits a police station with Interior Minister Gérald Darmanin this morning.

Borne has described last night's events as "intolerable and inexcusable".

We'll also be bringing you key updates on what she says, so stay with us.

An MP for President Macron's Renaissance party has told the BBC that the riots in France, in response to the police shooting of a teenager, are "out of proportion".

Natalia Pouzyreff told BBC Radio 4's Today programme that accusations of racism in the police didn't take into account the mixed racial backgrounds of many officers.

She accused some politicians of trying to exacerbate the situation:

"The police are not racist. The far-left parties are trying to put oil on the fire. They should call for appeasement and not try to encourage this anger and rage."

She added she believed the situation was a pretext for gangs to carry out looting:

"It's terrible... schools are burning. This violence is out of proportion for the situation."

This morning, the mayor of Toulouse, France’s fourth biggest city, invited several journalists including the BBC to give an update on the situation after a second night of rioting in the city’s suburbs which led to more than 20 arrests.

Jean-Luc Moudenc said it was a tiny minority of people on the affected housing estates who were behind the disturbances, and they were being egged on and encouraged by far-left extremists using the situation.

The mayor met the prime minister on Thursday in Paris to discuss the situation and told me he was worried an overreaction by the government to the disturbances could backfire and prolong the trouble.

He said a curfew in cities like his for the time being was not necessary and once again called for calm, saying the overwhelming majority of people on the housing estates impacted by the rioting simply wanted to get on with their lives and were the principal victims.

An only child brought up by his mother, Nahel, the French Algerian 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."

A leading member of one of France's main police unions has dismissed accusations that members of the force are racist.

It comes after Nahel M, a 17-year-old boy of Algerian descent, was shot dead during a traffic stop on Tuesday.

The violence seen over the last three nights has been fuelled by long-standing distrust between minority neighbourhoods and the French police, who they accuse of targeting them.

"You don't control people because of their skin colour. You proceed to control and arrest someone in consideration of the facts," Thierry Clair, the deputy secretary general of UNSAD-Police, told the BBC World Service's Newsday programme.

"No, the French police are not racist. There can be some behaviour which is on the borderline and some officers have been sanctioned, sometimes sacked, for such acts, but it's something that is marginal, like it happens in any corporation or institution."

He goes on to say his colleagues come from diverse backgrounds and many people have partners from other races and religions. He says it would be a "fallacy" to say the police as a whole are racist.

I speak to a Frenchwoman who is sweeping the floor of a small tobacco shop in Paris, severely damaged by last night's unrest; she has owned the store for 24 years.

“They came in the middle of the night. It was hundreds of people, who broke in and stole mainly cigarettes," she says.

She speaks to us through a smashed window.

“I live right upstairs, so I saw them coming and I heard everything. I was shocked.”

French Prime Minister Élisabeth Borne has described the events overnight in France as "unbearable and inexcusable" following a meeting with ministers this morning.

She tweeted , externalto reiterate her support in the police and other emergency services who are working "with courage" as the unrest continues.

French President Emmanuel Macron will convene his cabinet for a second crisis meeting in two days later, after the most widespread night of rioting yet across the country.

It comes as right-wing and far-right politicians have been demanding that a state of emergency be declared.

A state of emergency grants special powers to the authorities when the country's institutions are deemed to be "under threat". It allows the government to implement curfews and ban gatherings and public events.

The scale of the destruction seen across France this morning is likely to amplify calls for its implementation.

Senate Vice-President Roger Karoutchi has already tweeted to say that failing to declare a state of emergency would be "a mistake".

But the French government might be hesitant to take a step that has few precedents.

A state of emergency was called by then-president Jacques Chirac during the 2005 banlieue riots. That was the first time the measure had been taken in 50 years.

Ten years later, the French government declared a state of emergency following the 2015 Paris terrorist attacks. The measure lasted two years.

Yesterday, various government ministers said a state of emergency was not being considered.

Whether this is still their position as the unrest persists and intensifies remains to be seen.

Twelve buses were damaged in a suburb of Paris when a depot in Aubervilliers was targeted overnight.

The city's transport company RATP tweeted , externalthat "it condemns in the strongest terms this attack on assets essential to the operation of the public service".

It's warned its passengers that bus and tram services will be severely disrupted.

Transport minister Clement Beaune also expressed his dismay tweeting, external: "Attacking our transport means attacking the weakest who need our public services."

Some 249 police officers and gendarmes were injured in last night's riots, the ministry of the interior says.

It comes after France's interior minister said emergency services responded courageously to a night of "rare violence".

The situation this morning in Nanterre is very different.

Yesterday, the streets were dotted with cars that were burned, smashed and turned upside down.

Today, we woke up to the aftermath of looting in several parts of the Paris suburb.

A gas station has been broken into: there’s shattered glass on the floor and the security cameras have been smashed.

Across the street, a small tobacco shop has been destroyed.

Looting has taken place across France – including in Rue de Rivoli, which is near the Louvre Museum and the Champs Elysées.

This is a significant escalation in the unrest, which is not showing signs of calming down.

The mayor of Paris, Anne Hidalgo, will hold a crisis unit meeting at 09:00 local time (08:00 BST), according to French media outlet Le Parisien.

The capital was badly affected by last night's looting and rioting and public transport remains disrupted this morning.
