Three women behind a thwarted attack near Notre Dame Cathedral in Paris were radicalized by Islamic State commanders in Syria, and one had been engaged to an extremist who killed a priest in July, the Paris prosecutor said Friday.

Francois Molins spoke a day after the women were dramatically arrested over the failed attack that centered on a car discovered Sunday morning in central Paris abandoned and loaded with gas canisters. No detonators were found in the car.

“In the last few days and hours a terrorist cell was dismantled, composed of young women totally receptive to the deadly Daesh ideology,” Molins said, referring to Islamic State by its Arabic acronym.

The women suspected of spearheading the failed plot included Ines Madani, a 19-year-old whose father owned the abandoned Peugeot car. Her written pledge of allegiance to Islamic State was found by police, a security official said Friday.


Madani stabbed a police officer with a knife and was shot in the leg Thursday evening in a raid south of Paris, police said. She was being treated in a hospital.

Five women and two men have been arrested in the case.

One of the women detained in a police raid, referred to as Sarah H., was betrothed separately to two French extremists who carried out deadly attacks this year, the Paris prosecutor said.

Sarah H. was engaged to Larossi Abballa, who killed two police officials in Magnanville in June and filmed the aftermath on Facebook live before dying in a police raid.


She was also betrothed to Adel Kermiche, who slit the throat of an elderly French priest during morning Mass in July before being killed by police, Molins said. He didn’t say when she was engaged to either man.

France’s interior minister said the pursuit had been “a race against time” to find Madani and the two women with her before they could strike.

A man arrested Thursday also had ties to Abballa, one of the officials said.

“There’s a group that has been annihilated, but there are others,” French President Francois Hollande said Friday. “Information we were able to get from our intelligence services allowed us to act before it was too late.”


A security official, who was not authorized to be identified when speaking about the investigation, said Madani had pulled a knife during the raid outside a small apartment building near the Boussy-Saint-Antoine train station.

In video filmed by a neighbor, a veiled woman, her face uncovered, is seen being carried away by police as she cries out “Allahu akbar,” or “God is great.”

A plot conceived and carried out by a group of women would mark a new step in the Islamic State group’s attempts to sow fear in Europe.

“It’s at the same time rare and predictable,” Matthieu Suc, author of “Wives of Jihadis,” told France Info radio.


Women in the group do not take part in attacks, he said, but are there “to ensure the longevity of the caliphate” by having babies and providing moral support. But, he added, “there are often young girls, who are just as radicalized as the young men, and they also want the status of martyr, and they want to act.”

The car loaded with gas cylinders belonged to Madani’s father, who flagged her to police on Sunday, 14 hours after the vehicle was discovered. Since then, authorities have worked frantically to untangle the relationships within the group and thwart what they increasingly feared was another plot.

More than one-third of the nearly 700 French citizens who have reached the war zones of Iraq and Syria are women, according to government figures. And officials have said for months that those being recruited by Islamic State in France are increasingly adolescent girls and young women.
