SOUS-BOIS, France, Nov 4 (SPA)- Rioters set fire to hundreds of vehicles in an eighth night of unrest in the impoverished suburbs of northeastern Paris as exasperated local officials criticized the response of national leaders. Rioting erupted again late on Thursday despite hopes that festivities ending the fasting month of Ramadan would calm rioters, many of them Muslims of North African origin protesting against race bias they say keeps them in a second-class status, Reuters reported. Police reported fewer clashes than previous nights when police and fire crews were fired upon by some rioters. But the rioting continued to spread, with firebombing in western Paris suburbs and similar areas near Rouen in northern France, Dijon in the east and Marseille in the south.
