Al Qaeda has acknowledged that Osama bin Laden is dead, dispelling the doubts of some Muslims over whether the militant group's leader had really been killed by US forces, and vowed to mount more attacks on the West.

With their monstrous black sheep apparently 20,000 leagues under the Arabian Sea, it's back to business for the much misunderstood bin Laden clan. And for most of them - but not all, as we shall see - that business is making money. Ten years of living with the stigma of the most infamous surname in the world will have done little to boost profits for one of the Middle East's richest families.
