The violence erupted Oct. 27, 2005 following the accidental electrocution of two teenagers who hid in a power substation, apparently believing police were chasing them.
The anger spread to the Internet, with blogs mourning the youths.
Along with messages of condolence and appeals for calm were insults targeting police, threats of more violence and warnings that the unrest will feed support for France's anti-immigration extreme right.
Civil war is declared. There will no doubt be deaths. Unfortunately, we have to prepare, said a posting signed "Rania."
We are going to destroy everything. Rest in peace, guys, wrote "Saint Denis."
Until today more than 6,400 vehicles have been ignited, and one man has been killed. More than 1,600 rioters have been arrested.
