Some 50 masked attackers smashed cars and clashed with police in northeast Paris on Friday night. Three officers were injured, police said. The crowd had gathered at Place Gambetta in the city's working class 20th district to honor a young man killed during a police raid last month, according to the city police department. The group, some masked and armed with batons, then moved to the nearby Belleville neighborhood and smashed vehicles, including a police car, the police department said. Three police officers were injured in ensuing clashes, which lasted about 30 minutes, it said. No arrests were immediately reported. Tensions have remained high between police and French youth, especially minorities in rundown housing projects, since riots in 2005 that left cars ablaze in such neighborhoods nationwide. Most of that violence hit impoverished suburbs that ring French cities, while Paris was largely spared.
