are these unnamed youths Muslim and from Africa?

Categorically, monsieur, "Non!"

They are not Muslim and from Africa; their parents are from Africa, and they just coincidentally practice Islam.

And it is wrong for Westerners to call this 'rioting' or other prejudicial and pejorative terms; it is just a carefree celebration of the Islamic year-end Festival of Lights.

Please do not blame these youths for the fact that, when he cribbed it, Mohammed (Pork Be Upon Him) slightly misunderstood the concept.

Errrmm, I believe Diwali (the Festival of Lights) is a Hindu, rather than Mohammedan, observance.
