Rioters, angry over France's ban on Islamic veils for women, torched about 20 cars in a Paris suburb this weekend.
French police say about 50 attackers were involved in one rampage Saturday night in the town of Elancourt. Some of the rioters fought the police as others burned cars, garbage, and public property.
On Friday night about 250 people clashed with police in the town of Trappes, also protesting the Islamic veil ban.
The violence began after a group of residents gathered at the police station Friday to protest the arrest of a man whose wife was ticketed for wearing an Islamic face veil.
Officials say the husband had tried to strangle the officer who was doing the ticketing.
France has barred face veils since 2011. Proponents of the ban argue the veil oppresses women and contradicts France's principles of secularism, which are enshrined in the constitution.
