Une femme dangereuse
Frenchwoman Kenza Drider (32) has been one of the most vocal opponents of France's ban on the niqab.
On the day the law came into effect, she engaged in civil disobedience by taking the train from her home in Avignon to Paris while veiled. She spoke to the press at Notre Dame cathedral before being detained by police for taking part in an unauthorised demonstration.
