A fight broke out at a local festival in Clermont, starting with a stabbing then escalating to an exchange of gunfire between mobs of youths. Seven people were lightly injured by shotgun wounds, including two police.
One of the factions involved in the dispute was clearly Muslim. You can hear them speaking in Arabic in the video and saying "Allahu Akbar". I'm still not completely clear about who made up the other group, whether it was genuinely French people or Roma, but I think the latter.
Clermont, incidentally, is the place where the Pope gave a speech calling for the Holy Land to be liberated from Muslim rule. This was the start of the Crusades. At the rate things are going, we will soon need a crusade to liberate Europe from Muslim rule. In fact, looking at some of this footage, you might think the war had started already.
