PARIS - Hundreds of black-clad protesters clashed with police at the end of a demonstration against police violence in Paris on Saturday after masked protesters launched fireworks at police lines, put up barricades and threw stones.

The majority of the thousands of demonstrators marched peacefully, but small groups of masked protesters dressed in black smashed shop windows and set two cars, a motorcycle and a cafe on fire. The fires were put out quickly.

Police fired tear gas and stun grenades to disperse the crowds and in early evening water cannon sprayed remaining groups of protesters on Place de la Bastille.

The interior ministry said it had counted 46,000 protesters in Paris. Police said they had made nine arrests.

Thousands of people also marched in Lille, Rennes, Strasbourg and other cities.

The protests follow the publication this week of CCTV footage of the minutes-long beating of Black music producer Michel Zecler by three police officers in Paris on Nov. 21.
