French Interior Minister Manuel Valls on Saturday denounced the violent clashes erupted after police arrested a woman wearing a full face veil. \"Nothing justifies this violence. Its is unacceptable. Attacking police, institutions and public properties make no sense. It does not solve any problem,\" Valls said. In a visit to the southern town of Marseille, the minister noted that \"the order was restored\" in the Paris suburb of Trappes where reinforced police units will be deployed during the weekend. Last night, about 250 protestors clashed with police after a man atttcked an officer who wanted to verify the identity of his full-veil -covered wife. Three policemen were slightly injured during the clashes. A 14-year-old boy was seriously wounded in his eye by a shot from a Flash-ball whose origin rermained unkown, according to Versailles prosecutor, Vincent Lesclous. Six people were arrested and placed in custody, he added. In April 2010, France\'s ban on full face veils, a first in Europe, went into force, exposing anyone who wears the burqa in administrations, hospitals and parks to a fine worth 150 euros (197 U.S. dollars), or a forced citizenship lesson. Men forcing their wives to wear the Muslim niqab will have to pay a 30,000-euro fine, and may face one year in prison. According to figures of the Interior Ministry, about 1,900 Muslim women are wearing the burqa across France, which has the biggest Muslim community in the European Union. France has already banned Muslim headscarves and other religious symbols in schools. It\'s is the second European country after Belgium to ban the wearing of a veil.
