As France is stricken with violent protests following the police shooting of a teenager, the economic costs are adding up. In the southern city of Marseille, where some of the worst violence and looting has been reported, the local Chamber of Commerce has revealed that over 400 businesses were vandalized and damaged.

In an interview with France Info on Sunday, the head of the Chamber of Commerce for Aix-Marseille-Provence, Jean-Luc Chauvin, said, “All types of businesses have been targeted, especially those with valuable merchandise.” He added that the initial assessment by insurers estimated that the cost of the damage would be more than €100 million ($109 million), and that number will undoubtedly rise as assessments continue.

He noted that some stores would take months to repair their damage and reopen, especially those which were set on fire, or who saw their entire stocks looted by rioters.

The rioting began Tuesday, following the shooting of a teenager by police in the Paris suburb of Nanterre. The teenager, a 17 year old French-Algerian the media has identified as Nahel M., had attempted to run a police traffic stop in his vehicle, when an officer shot him.

The officer who pulled the trigger has been arrested and charged with homicide, however the incident triggered mass protests among the Muslim population of France, and protests quickly spilled over the borders into Belgium and Switzerland.

After youth overran streets, burning vehicles, and looting and vandalizing stores, starting fires, and attacking police officers, French authorities deployed 45,000 police to quell the riots.

In the six day period of riots spanning from June 30th to Monday, the number of arrests reportedly fell from 3,800 down to 157, according to the French Interior Ministry.
