The woman who died during a raid in Saint Denis was vulnerable and fragile, according to one of her school friends.

Hasna Ait Boulahcen had written on Facebook that she wanted to go to Syria, but her friend - who gave her name only as Khemissa - said she did not believe her.

She added: "I don't think she was in a normal state. I think she must have been drugged. She must have taken substances. She was not in a normal state, otherwise she wouldn't have done that."

The raid followed gun and suicide bomb attacks in the French capital on 13 November that left 129 people dead.
