Excerpt:
French riot police remain stationed in the riot-weary Paris suburb of Trappes, following weekend violence after a woman was stopped Thursday by police for wearing a face-covering niqab.
Interior Minister Manuel Valls said French riot police remained on full alert Monday and will stay in place as long as necessary, adding that the violence has now been "contained".
He also defended the country's hotly contested ban that has outraged many in France's Muslim community.
