CNN) -- Saber-rattling al Qaeda warnings against the United States emerged Friday as Osama bin Laden's killing yielded a trove of ominous intelligence, including details about a possible attack on the 10th anniversary of 9/11.
Al Qaeda, the bin Laden terror network that masterminded the deadly attack on the U.S. 10 years ago, confirmed its leader's death on Friday in a Web statement, using that opportunity to taunt and threaten the United States.
"Sheikh Osama didn't build an organization that will vanish with his death or fades away with his departure," according to the statement, which CNN could not independently authenticate.

The statement, which congratulates the "Islamic Nation on the martyrdom of their devoted son Osama," repeated themes and threats made over the years in al Qaeda statements, before and after the September 11, 2001, attacks.
"The blood of the mujahed sheikh, Osama bin Laden, may God have mercy on him, is very dear to us and more precious to us and to every Muslim from being shed in vain," the statement said. A mujahed is defined as a Muslim engaged in what he considers to be jihad.

"This blood will be a curse that will chase the Americans and their agents, a curse that will pursue them inside and outside their country, and soon -- with God's help -- we pray that their happiness turns into sorrow and may their blood mix with their tears and let Sheikh Osama's resonate again."
