The Saudis and French seem to think so:
Osama bin Laden is dead. At least according to Saudi intelligence sources cited by a French newspaper, which in turn claims to have obtained a document leaked to them by French counter-intelligence services.
The news of the death of al-Qaida's chief was reported in the Saturday edition of l'Est Republicain, a respected regional daily. The French paper cites a memo they claim was obtained from the French counter-espionage agency, the Direction Générale des Services Extérieurs, or the DGSE.
(The story was first broken this morning by Talking Points Memo.)
