Bin Laden Death Confirmed By Al Qaeda

Al-Qaida confirmed the killing of Osama bin Laden Friday and vowed revenge, saying Americans' "happiness will turn to sadness" in the first statement by the terror network since its leader was slain in a U.S. commando raid against his Pakistani hideout.

The confirmation came as newly uncovered documents found in bin Laden's residence revealed al-Qaida plans for derailing an American train on the upcoming 10th anniversary of the Sept. 11 attacks.
Terror experts have said bin Laden's death on Monday was a setback for al-Qaida but the threat of attacks remains and could even spike in coming days from individuals or small extremist groups inspired to take revenge for the killing.

The statement, dated Tuesday but posted Friday on militant websites, 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 a likely contender to take his place.

"The blood of the holy warrior sheik, Osama bin Laden, God bless him, is too precious to us and to all Muslims to 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."
