Al Qaeda has recognized that Osama Bin laden is dead and warned on their website of a possible retaliation.

CAIRO -- Al Qaeda on Friday confirmed the killing of Usama bin Laden and warned of retaliation, saying Americans' "happiness will turn to sadness."

The confirmation came in an Internet statement posted on militant websites, signed by "the general leadership" of Al Qaeda. The announcement opens the way for the group to name a successor to bin Laden. His deputy Ayman al-Zawahri is now the most prominent figure in the group and is a very likely contender to take his place.

The statement, dated May 3, was the first by the terror network since bin Laden was killed Monday by U.S. commandos in a raid on his hideout in Abbottabad, Pakistan. The statement's authenticity could not be independently confirmed, but it was posted on websites where the group traditionally puts out its messages.

"We stress that the blood of the holy warrior sheik, Usama bin Laden, God bless him, is precious to us and to all Muslims and will no go in vain," the statement said. "We will remain, God willing, a curse chasing the Americans and their agents, following them outside and inside their countries."

"Soon, God willing, their happiness will turn to sadness," it said, "their blood will be mingled with their tears."

There was no indication how the group will retaliate. Rather than making vehement cries of vengeance, the statement -- entitled "You lived as a good man, you died as a martyr" -- struck a tone of calmness and continuation. Though it included praise of bin Laden, much of the 11-paragraph statement was dedicated to underlining that Al Qaeda would live on, depicting him as just another in a line of "martyrs" from the group.
