Unrest across France sparked by the police shooting of a 17-year-old appeared to slow on its sixth night, but fires and vandalism continued to target public buildings, cars and municipal trash cans overnight into Monday. The Interior Ministry says there were 157 arrests overnight out of a total of 3,354 since last Tuesday, and that two law enforcement stations were attacked, among other damage. About 45,000 officers were deployed nationwide to counter anger over discrimination against people who trace their roots to former French colonies and live in low-income neighborhoods. Nahel, the teenager killed last Tuesday, was of Algerian descent and was shot in the Paris suburb of Nanterre.

Recent high-profile mass shootings by young people underscore the deadly mix of teenage bravado, immaturity and growing access to high-powered guns that can kill faster and more efficiently than ever.

France's Interior Ministry says that 1,311 people were arrested around the country during a fourth night of riots triggered by the deadly shooting of a 17-year-old by police. The government deployed 45,000 police around the country to try to quell violence. Overnight young protesters clashed with police and set some 2,500 fires and ransacked stores. The funeral ceremony for Nahel began Saturday with a visitation to be followed by a mosque ceremony and burial. He was killed by police in the suburb of Nanterre on Tuesday.
