Kenza Drider, a niqab veiled young woman from the southern city of Avignon, is surounded by media in front of Notre Dame Cathedral in Paris, France, April 11, 2011. France's ban on full face veils, a first in Europe, went into force today, exposing anyone who wears the Muslim niqab or burqa in public to fines of 150 euros and lessons in French citizenship.
