After almost a week, unrest in France sparked by the police shooting of a 17-year-old appeared to slow, but fires and vandalism continued to target public buildings, cars, and municipal trash cans on Monday.

In all, according to the Interior Ministry, there have been over 3,350 arrests since last Tuesday following a mass security deployment aimed at quelling France’s worst social upheaval in years.

The riots appeared driven by a teenage backlash. The interior minister said the average age of those arrested was 17 and that children as young as 12 or 13 had been detained for attacking law enforcement and setting fires.

There has been little in the way of organized protests beyond a march last week for Nahel, the teenager killed last Tuesday. But many activists say the nighttime riots are a lashing out against a French state that many young people with immigrant roots say routinely discriminates against them. Nahel was of Algerian descent and was shot in the Paris suburb of Nanterre.

About 45,000 officers were deployed nationwide to counter violence fueled by anger over discrimination against people who trace their roots to former French colonies and live in low-income neighbourhoods.

In all, a total of 99 city halls have been attacked, according to the Interior Ministry.

However, while concerts at the national stadium and smaller events around the country were cancelled because of the violence and some neighbourhoods suffered serious damage, life in other parts of France went on as usual.

In the capital, tourists thronged to the Eiffel Tower, where workers set up a nearby clock counting down to next year’s Paris Olympics. A short walk from Nanterre, a shopping mall bustled Sunday with customers from all walks of life. Families who could afford it headed for summer vacation.

French President Emmanuel Macron has blamed social media for the spread of the unrest and called on parents to take responsibility for their teenagers. Justice Minister Eric Dupond-Moretti told France Inter radio that parents who abdicated that responsibility “either through disinterest or deliberately” would be prosecuted.
