Debka: OBL Dead?

Debka has reported (again) that Osama bin Laden may be dead, according to a recent bulletin:
DEBKAfile’s Exclusive Islamic and Intelligence sources report:
An announcement of Osama bin Laden’s death appears Friday in one of his close aides’ most credible Web sites. It has sparked a storm of controversy in al Qaeda circles, some of whom claim notice is false.
Signed by the Pen of Jihad Warriors, the site provides no information on circumstances of death, only asks:
Where are those who break out of borders? Where are the lamenters? Where are those who throw themselves from the tops of towers and skyscrapers? Where are the heart-rending cries?
Egyptian bin Laden adherent, Yasser Sari, calls notice a lie and promises new videotape soon in which leader announces end of al Qaeda truce in Europe. Other followers credit the announcement as “authentic and Islamic.”
