'A calmer night in Paris'
Fears of further violence in the French capital on Friday night seem to be have been averted, Le Monde newspaper reports.
It says massive police deployments have deterred would-be rioters, and only sporadic incidents such as burning rubbish bins and attempts at looting have been reported. Police say 120 people have been arrested in Paris overnight, according to the newspaper.
Violence has continued in suburban areas and other cities such as Marseille and Lyon, however.

Canadian Prime Minister Justin Trudeau spoke to President Macron on Friday, his office said.
The two leaders spoke on a range of issues: Their support for Ukraine, the ongoing crisis in Haiti, the French firefighters helping on the ground as Canada battles a record breaking wildfire season.
But the readout came with a short nod to the demonstrations that have roiled France now for days, saying Trudeau “acknowledged the difficult situation in France due to ongoing protests”.
We are seeing a downturn in violence - interior minister

French Interior Minister Gérald Darmanin says tonight has been far calmer than Thursday despite there being at least 471 arrests so far.
Speaking during a night visit to Yvelines west of Paris, he told a member of the gendarmerie that they were seeing a "downturn" in violence.
The violence was of "much less intensity" and it was "extremely calm" in some departments, he said.
This comes amid widespread chaos being reported in cities across France, with the interior ministry putting the number of arrests at least 471 tonight.
More than 900 people were arrested the previous night.

Come to Nanterre to get an all-round view of the crisis boiling over in France. But if you are a journalist, be advised to keep your head down.
An approach to a group of young men - some bearded, one built like a bodybuilder - outside theLe 35café prompts an aggressive outburst of swearing and a pointed finger directing me to keep out.
At the scene where police shot dead a 17-year-old boy of Algerian descent last Tuesday, women in Islamic headscarves shout abuse at police and the media from passing cars.
Wandering through the streets incognito - without a camera or notebook - past burned-out cars and smashed premises it is possible to pick up glimpses of the last catastrophic few days.

More from Marseille now, where there have been at least 80 arrests overnight.
Videos have been uploaded to social media showing an explosion at the city's old port. City authorities said they were investigating the
cause but did not believe there were any casualties.
Footage is also circulating of what appears to be an Aldi supermarket being rammed with a van before people run inside. Separate footage then appears to show the supermarket on fire.
Rioters earlier looted a gun store in the city and
stole hunting rifles but no ammunition, police said.
Marseille Mayor Benoit Payan called on the national
government to immediately send additional troops.
"The scenes of
pillaging and violence are unacceptable," he tweeted late on Friday.
Interior Minister Gerald Darmanin later tweeted that reinforcements were "arriving at this moment".
Rioting spills over into Belgium

Rioting in France has spilled over into Belgium, with dozens of arrests being reported.
France's Le Monde newspaper said that 100 people were arrested in the capital Brussels on Friday, while some 30 arrests also took place in the city of Liège.
More than 60 people were also arrested in Brussels on Thursday.
Young teenagers implicated in violence
Let's recap one of the most interesting aspects of this story to emerge in the last few hours.
Children as young as 13 have been arrested during the riots in France, the interior minister said earlier during an appearance on France's TF1 channel.
Gérald Darmanin also said the average age of the more-than-900 people arrested on Thursday night was 17.
Earlier, President Macron called on parents to take greater responsibility for their children and keep them out of the riots.
Geneva cross-border transport not running
Geneva's cross-border buses and trams were not running into France on Friday evening, after the French government called on regional authorities to halt those transport methods after 21:00 local time (19:00 GMT).
The eastern Swiss city is surrounded by France on three sides and many of its public transport services run across the border.
Some lines were halting at the border, and three cross-border routes were stopping altogether, the AFP news agency reports.
How did all this start?
France is seeing more overnight unrest, several days after the police killing of teenager Nahel M in a Parisian suburb.
On Tuesday morning, the 17-year-old was fatally shot in the chest, point-blank, at the wheel of a Mercedes car - after driving off during a police traffic check.
When he was stopped by police, he was in a car with Polish number plates and two passengers. At 17, he was too young to have a driving licence.
"What am I going to do now?" his mother asked, "I devoted everything to him".
Footage of the incident has been widely shared across social media, leading to four nights of violence across France and the government deploying 45,000 police officers tonight to tackle the disruption.
A total of 270 people were arrested across France on Friday daytime and evening, Interior Minister Gerald Darmanin said. In the early hours of Saturday, the ministry updated that figure to 341.
At least 80 of those are in Marseille, where Mayor Benoit Payan has asked the central authorities for police reinforcements to deal with the unrest.
Looting has also been taking place in the cities of Lyon and Grenoble with groups of often hooded rioters raiding shops.

A fourth night of riots is, as feared, taking place in France. Let's look back at what's been happening over the last few hours.
Gérald Darmanin, the interior minister, said the government had deployed 45,000 police officers overnight to quell any further unrest
The government also called on regional authorities to shut down overnight bus and tram services nationwide
Major events such as festivals and Pride celebrations have been scrapped - including concerts at the State de France by singer-songwriter Mylène Farmer - a big name in the French-speaking music world
Police again confronted protesters in the evening - arresting at least 270 people nationwide including 80 in Marseille, and working to break up a public demonstration at the Place de la Concorde in Paris
Authorities have made repeat calls for parents to keep children out of the unrest, with Darmanin saying teenagers as young as 13 were arrested on Thursday
Mbappe calls for rioting to end

French football star Kylian Mbappe has called for the rioting to end.
Mbappe, one of the world's best players who is currently at Paris St Germain, tweeted that "we cannot remain insensitive to the circumstances in which this unacceptable death took place".
But he added that "violence solves nothing".
"It is your property that you are destroying, your neighbourhoods, your cities, your places of fulfilment and proximity," Mbappe wrote.
"There are other peaceful and constructive ways to express yourself. It is in this that our energies and our reflections must be concentrated. The time of violence must end to make way for that of mourning, dialogue and reconstruction."
Mbappe was raised in Bondy, a northeastern suburb of Paris.
Busy night for cab drivers after shutdown of public transport
Insaf Abbas
Reporting from Paris
Taxi drivers here in Paris and across France are
having a busier night than usual, following the nationwide suspension of bus
and tram services.
People leaving Paris Gare du Nord are
frantically trying to book Ubers, while others have been jumping in taxis waiting
outside the station. The bus stops are empty.
When I approach a driver and ask to go to
Nanterre, the epicentre of the protests, he looks at me in shock. “Nanterre!
Too dangerous.”
I then head towards a group of drivers, who
laugh - with one saying he’ll take me there for €250 (£215).
Eventually one agrees to take me for a (far)
more reasonable price.
The 30-minute journey is quiet - the only sign
of the protests is a burnt vehicle on the side of a road, and police cars
driving past us, heading further into the district.
Marseille rioters raid gun store - report
More now from Marseille - where at least 80 people have been arrested tonight, as we mentioned earlier.
Rioters also looted a gun store, the Reuters news agency quotes police as saying.
The looters are said to have taken away some hunting rifles, but no ammunition.

How tonight's policing numbers compare
As we've been reporting, France is sending out 45,000 police officers tonight in anticipation of a possible fourth night of unrest across the country.
It's a number that's been building. Last night, the equivalent figure was 40,000. On Wednesday, it was 9,000.
According to the government, 249 officers have been injured during clashes over the last few days.
Thursday night saw at least 917 people arrested, according to the interior minister.
Eighty more arrests in France's second-largest city
Despite public demonstrations being banned in the southern city of
Marseille, clashes have occurred today between protesters and riot officers.
At
least 80 people have been arrested, according to the latest tweet from police - who earlier reported that "many violent
groups" remained in the city centre, and urged people to leave the area
Marseille's Pride
event, which was scheduled for Saturday, is just one of many major events nationwide to have been called off - in
part due to police resources being diverted
The Acontraluz music festival, too, posted on social media to say its performances on Friday night had been halted
And
all public transport was requested to halt at 19:00 local
time (17:00 GMT)
Why are police using guns during traffic stops?
Laura Gozzi
Live reporter
On Tuesday, police shot dead Nahel M, 17, as he drove away from a traffic stop, leading to three nights of riots across France.
By law French police are allowed to shoot in five instances following a 2017 change in the law.
That includes when the driver or occupants of a vehicle ignore an order to stop and are deemed to pose a risk to the officer's life or physical safety, or other people's.
