That's a fair point. It doesn't say in the article who did it.
But, I would point out these incidents took place on the heels of the Israeli military "crackdown" (for want of a better word) on Arafat. Also, as has been pointed out, Marseilles has a very large Muslim population. It seems to me that perhaps the BBC has purposefully omitted the fact that at least an eye should be cast towards the Muslim community in France. Instead they are very faithful to the Kristalnacht metaphor- leading one to think along Right Wing Fanatic lines. Lionel Jospin certainly wasted no time condemning the acts and I'm sure he could only benefit by making certain the public thinks the Right Wing is responsible. Hey, it might turn out that they were.
But given the Islamic rap sheet of late- they are "the usual suspects" and someone will need to show me that they weren't behind it.
