Three brothers were involved and one may still be at large.
Terror has just gripped Paris once more after false reports of gunfire sent people running for their lives.
A British victim of the terror attacks has been named. Nick Alexander, 36, from Colchester, Essex, was selling merchandise for US rock band Eagles of Death Metal at the Bataclan concert hall.
In New York, Polina Buckley revived her dormant Twitter account in an attempt to find out what had happened to her British boyfriend, Nick Alexander. He had travelled to Paris as the merchandise seller for US rock band Eagles of Death Metal.
“Someone please help me find my boyfriend Nick Alexander #Bataclan #ParisAttacks,” she wrote. A few minutes afterwards, she posted a picture of a long-haired, bearded man smiling at the camera.
Others posted similarly heartbreaking pictures of children, parents, cousins, friends and lovers they desperately hoped were still alive.
“My friend Guillaume”; “my sister Soad”; “Valeria, an Italian” read some of the search notices multiplying under the hashtag #rechercheParis.
“Lucie Dira, 12 years old,” said one simply, above the pensive face of a pre-teen girl, one of the youngest missing.
Within a few hours of posting her message, Polina discovered that her boyfriend had been among the 89 people killed at the Bataclan concert hall when three terrorists forced their way into the venue and opened fire. When police stormed the building, one terrorist was shot but two managed to detonate suicide bombs.
On Saturday night Alexander’s family issued a statement confirming that the 36-year-old from Colchester had been killed – the first Briton to be named among the Paris dead. “It is with huge sorrow that we can confirm that our beloved Nick lost his life at the Bataclan last night,” the Alexander family’s statement said. “Nick was not just our brother, son and uncle, he was everyone’s best friend – generous, funny and fiercely loyal.
Britain has said there may be "a handful" of British victims.

A harrowing image has emerged from inside the Bataclan theatre where terrorists opened fire on concertgoers on Friday night - killing at least 89 people and injuring dozens, possibly hundreds, more.
The photograph, taken in the wake of the attack, details the blood stained interior of the concert hall where bodies remain lying on the ground and the floor is covered in debris.
It comes as new footage shows the moment the members of U.S. rock band Eagles of Death Metal stopped their performance midway through a song when gunfire broke out.
The violence at the Bataclan unfolded as part of a series of co-ordinated ISIS attacks across the heart of Paris on Friday evening in the worst violence to strike France since the Second World War.
At least 132 people are dead, and another 349 injured, after the three teams of jihadis attacked the Stade de France football stadium, a handful of bars and cafes, and then finally the Bataclan concert hall.

Harrowing footage of the moment the jihadis opened fire at the Bataclan concert hall shows the band's drummer and two guitarists on the darkened stage, illuminated only by the flashing stage lights.
Suddenly, gunfire erupts.
What sounds like a loud popping noise - which survivors said they at first mistook for fireworks - breaks out to the band's left. They instantly stop playing as the horror of what is unfolding before them sinks in.
One of the guitarists then flees the stage, while the drummer jumps down behind his drum kit for cover. All band members have since been confirmed safe and accounted for by a US official, and they left Paris yesterday evening.
But 89 people were killed when the terrorists carried out the shooting inside the theatre, in what was the deadliest flashpoint in a series of co-ordinated attacks across Paris. It is not clear who recorded the video, or if they survived.
Pierre Janaszak, a radio presenter who was at the concert, said: 'They didn't stop firing. There was blood everywhere, corpses everywhere. Everyone was trying to flee.'
He added: 'I clearly heard them say "It's the fault of Hollande, it's the fault of your president, he should not have intervened in Syria".'
The Foo Fighters, who were due to play in the French capital tomorrow night, Lyon on Tuesday night and Barcelona on Thursday night have cancelled the rest of their tour following the attacks.
Irish rockers U2 have also cancelled their Paris shows while alternative metal group Deftones were set to play a three-night run at the terror-hit Bataclan.
Meanwhile, on the second day after the worst terror attack in French history it has emerged:
French police are hunting for two gunmen on the run after Friday's attacks and an ISIS bombmaker likely to have made the suicide vests.
Car used in drive-by shootings at two restaurants found abandoned containing three AK-47s with five full magazines and 11 empty ones.
One of Bataclan suspects was found carrying Syrian passport under the name Ahmed Almuhamed who travelled to France as a migrant through Greece. Ferry tickets reveal he travelled with another man named as Mohammed Almuhamed.
Frenchman Omar Ismaël Mostefai, 29, also named as a Bataclan suicide bomber who was identified by his severed finger. Mostefai's father, a brother and other family members have been held and are being questioned.
The eight-strong ISIS cell alleged to have included three brothers who may all have gathered in a Belgian suburb called the 'Jihad capital of Europe' to collect their AK-47s and suicide vests.
Bataclan survivors claim that one of the four shooters was a woman.
Seven people were detained in Belgium linked to the atrocities - three at the border and four in Brussels.

At least 132 people died in Paris on Friday night after eight terrorists, including one as young as 15, carried out the co-ordinated attacks. They struck the Stade de France, restaurants, and the packed Bataclan concert hall armed with AK-47s, grenades and wearing suicide vests.
Serbian media claim Ahmed Almuhamed, 25, whose Syrian passport was found on the body of a suicide bomber, allegedly blew himself up at the Bataclan concert hall.
The newspaper Blic claims he arrived with another of the bombers in Europe on the Greek island of Leros on October 3 on his way to Paris. Greek website Protothema has published ferry tickets showing the name of a second man, Mohammed Almuhamed, who could be a relation.
Survivors have also claimed a woman was among the group shooting randomly into the crowd at the gig before the three blew themselves up and a fourth person was shot dead by police before they could detonate their bomb.
Another one of the attackers was named locally as homegrown terrorist Omar Ismaël Mostefai, 29, from Courcouronnes, Paris. The petty criminal was known to police as a radical and identified by the fingerprint on a severed digit found after he detonated his suicide belt.
It is believed two of the bombers were carrying Syrian passports. At least two others are believed to be French while several could also be Belgian.
The disclosure that some may have entered Europe as migrants, which came amid claims of French intelligence failures, inevitably raises new security concerns about the safety of Europe's borders.
