Dramatic footage has emerged of the final moments of Europe's first female suicide bomber as she screamed 'he's not my boyfriend' at police seconds before blowing herself to pieces.
Hasna Ait Boulahcen's head was sent flying out of a window and her spine landed on a police car when she detonated an explosive vest during a fierce gun and grenade battle with French commandos.
A new clip, obtained by ABC news, shows how the dramatic events unfolded early on Wednesday morning.
Anti-terror police can be seen creeping around the side of the building as red lights from police guns can be seen trained on a window in the apartment block in Saint-Denis.
Throughout the short clip the sound of gunfire can be heard, and there is some muffled shouting before a massive explosion blows out the top-floor window.
That is the moment Ait Boulahcen, 26, the cousin of Paris massacre ringleader Abdelhamid Abaaoud, is believed to have detonated her suicide bomb.
The video emerged just hours after audio footage from the scene captured her exchange with French police.
In it, an officer shouts to her: 'Where is your boyfriend?', seemingly directed at reports which initially surfaced that Ait Boulahcen may have been Abaaoud's jihadi bride.
She screams back: 'He's not my boyfriend!'
The officer yells again: 'Where is he?' to which Ait Boulahcen replies with the same answer: 'He's not my boyfriend!'
Seconds later an explosion is heard as she detonates her suicide vest during the siege.
The audio emerged as family and acquaintances gave extraordinary accounts of a young woman who was known for her love of alcohol and cigarettes rather than devotion to Islam.
Her brother Youssouf Ait Boulahcen said that she had had no interest in religion, never read the Koran and had only started wearing a Muslim veil a month ago.
A photograph has also emerged of Ait Boulahcen posing for a selfie in the bath. Her face is covered in heavy make-up and she wears nothing but jewellery.
Ait Boulahcen was killed along with her cousin Abaaoud during a ferocious six-hour firefight with police.
She detonated a suicide vest after screaming 'help me, help me!' at officers, while 27-year-old Abaaoud was first hit in the head by a police sniper and then blown to pieces by numerous grenades.
Abaaoud, who is suspected of masterminding the Paris terror attacks which killed 129 people, was a committed jihadist who had been in Syria and was well-known to the European authorities.
However, his cousin appears to have only become radicalised in the last month after abandoning her former lifestyle to join ISIS.
In a statement, her brother Youssouf, said that he had never even see her open the Koran.
'She was living in her own world. She was not interested in studying her religion', he said. 'She was permanently on her phone, looking at Facebook or WhatsApp.
'I told her to stop all of this but she would not listen, she ignored my numerous attempts to give her advice telling me I was not her dad, or her husband, and so I should leave her alone.'
Ait Boulahcen's family arrived in France in 1973 and settled in Paris, where she was born in 1989 in Clichy-la-Garenne, a suburb close to Wednesday's gun siege.
Her parents had separated when she was young and she had been brought up by foster families. Her mother, whose first name is not known, lives in a tower block in Aulnay Sous Bois, a suburb 20 minutes outside of Paris.
It is understood that although Ait Boulahcen visited often, she did not live there permanently.
Friends said she remained 'close' to her father and would regularly visit his home in Creutzwald, Moselle. She lived with him for two months.
Local resident Amin Abou, 26, described her as 'a party animal who loved clubbing'.
'I would see her in this club in Germany which is only ten minutes away but where we go out because its much cheaper for alcohol.
'She came here two or three years ago for two months. She didn't work or go to university. I don't think she even finished school.
'She loved partying and going to clubs. She drank alcohol and smoked and went around with lots of different guys. She had a bad reputation. She had lots of boyfriends, but nothing serious’.
Another friend Mattius Jacques, 24, said: 'She was normal she wore Western clothes, she never wore hijab. She didn't go to mosque or pray. She never spoke about news or Palestine or anything.
'She wasn't religious at all. She was like you and me, she went out, she lived a free life, always out partying.
'Her dad didn't mind, he's cool. He plays guitar. Her father worked in car factory but is now retired. He goes to mosque often but he's not strict. He goes on holiday to Morocco often because he lives alone.'
Friends also described her as a fun-loving party girl who liked to drink alcohol and was nicknamed 'the cowgirl' due to her love of wearing big cowboy hats.
Neighbours at the building where Ait Boulahcen's family live, in a run-down suburb of Paris, said that she had been there three weeks ago.
Confirmation of her death came around the same time prosecutors identified her cousin as being one of two terrorists killed in the raid on a flat in Saint Denis.
Forensic experts had to identify Abaaoud through saliva samples and pieces of skin because his body was so badly disfigured.
His presence in the heart of the French capital stunned France and has raised serious questions about security across Europe after it was thought he had been in the Middle East all along.
French Prime Minister Manuel Valls said the attackers had exploited the refugee crisis to 'slip in' to France and warned the EU's passport-free zone – under the Schengen agreement – would be 'undermined' if Europe did not tighten security at its external borders.
It also emerged today that Abaaoud was filmed taking the Metro without a ticket on the night of the bloodbath.
The 27-year-old was one of the world's most wanted Islamic State criminals at the time, yet was unchallenged as he jumped automatic barriers on Line 9 of the city's underground train system.
The CCTV was captured at 10pm, while suicide bomber members of his ISIS cell were destroying lives all over Paris with explosives and automatic gunfire.
Today also saw an early morning counter-terrorism raid on a mosque in the western port city of Brest.
Hundreds of heavily armed police officers could be seen storming the place of worship in the district of Pontanezen.
It came as EU chiefs prepared to meet on the week anniversary of the attacks to discuss the alarming security breaches that allowed Abaaoud to strike.
Abaaoud was thought to be in Syria, yet was in fact travelling backwards and forwards to the Paris area, where he co-ordinated up to six terrorist attacks over the past year alone.
He posed as an asylum-seeking migrant without papers as he brazenly smoked pot and drank openly in the streets of greater Paris, including in the days after the attacks, according to witnesses.
The Metro CCTV footage was shot at the Croix de Chavaux station, close to the Paris suburb of Montreuil, last Friday.
Abaaoud jumped the Metro entrance barriers without a ticket at the station, which is just 200 yards from the place where a Seat car was later found abandoned with three Kalashnikov rifles inside.
The jihadi went into hiding after the attacks, before he was himself killed by police commandoes during a police raid in the nearby suburb of St-Denis on Wednesday morning.
His body was torn to pieces by bullets and grenades, meaning it took more than 24 hours for forensic tests to confirm he was dead.
Abaaoud died alongside his cousin, Hasna Aitboulahcen, 26, who was also living openly in the Paris suburbs as she helped plan the attacks.
Aitboulahcen became Europe's first ever female suicide bomber as she tried to take police officers with her during the St-Denis assault.
Today the French government was desperately trying to explain how such murderous criminals were allowed to operate so freely in the country.
Referring to Abaaoud, who was based in Belgium for much of his life, Interior Minister Bernard Cazeneuve said he was baffled as to how he managed to routinely get into France overland from Syria.
Mr Cazeneuve said: 'Not a single piece of intelligence from a European country that he might have transited through before arriving in France was communicated to us suggesting that he might be in Europe and was heading towards France.'
As he defended the performance of his security agencies, Mr. Cazeneuve pleaded for more intelligence sharing, saying, 'It is urgent for Europe to come together' and to 'Wake up!
Further details have also emerged about the links between Abaaoud and his fugitive accomplice, Salah Abdeslam, who fled after the attacks.
The two men previously appeared together in a Belgian court for burglary after a drunken night out, according to lawyer Alexandre Castle, who represented Abaaoud against a raft of charges including robbery, assault and handling stolen goods from 2006 and 2013.
The announcement that one of the world's most wanted men was dead followed a warning by France's prime minister that ISIS could unleash a chemical attack on the country.
Manuel Valls made the ominous prediction while calling on French MPs to extend the country's state of emergency for another three months.
He said militant jihadists linked to the terrorist cell that carried out the attacks in Paris last week possessed the capability to strike with chemical and biological weapons.
He said: 'The macabre imagination of the masterminds is limitless.'
Mr Valls' warning comes as U.S. security officials report that they have found proof that ISIS is developing bioweapons with the help of Syrian and Iraqi scientists in the Middle-East.
