Osama: I Sent The Underwear Bomber

Osama bin Laden released a tape today claiming responsibility for the failed underwear bomber.

The one-minute message was explicit in its threat of new attacks. Like the airline plot, bin Laden said they would come in response to America's support for Israel. "God willing, our raids on you will continue as long as your support for the Israelis continues," bin Laden said in the recording, which was released to the Al-Jazeera news channel. "The message delivered to you through the plane of the heroic warrior Umar Farouk Abdulmutallab was a confirmation of the previous messages sent by the heroes of the Sept. 11," he said of the Nigerian suspect in the Dec. 25 botched attack. "If our messages had been able to reach you through words we wouldn't have been delivering them through planes."

American intelligence officials said the tape's authenticity could not be immediately verified.
