WASHINGTON DC (AP) -- The White House says an audio recording purported to be from Osama bin Laden hasn't been authenticated yet, and the president's spokesman isn't commenting on the claim that the al-Qaida leader was behind the Christmas Day airline bombing attempt.
But a senior U.S. intelligence official says there's "no evidence whatsoever" that Osama bin Laden had any involvement in the plot to bomb the Detroit-bound airliner.
The minute-long recording was carried by Al-Jazeera Arabic news channel. In it, Bin Laden addresses President Barack Obama and says the failed Christmas attack was meant to send a message similar to that of the Sept. 11 attacks. He threatens more attacks, saying they will never stop as long as America supports Israel and Palestinians remain without a secure homeland.
White House adviser David Axelrod tells CNN's "State of the Union" that whatever the source, the message "contains the same hollow justification for the mass slaughter of innocents."
