Bin Laden takes credit for airline bombing plot; officials express skepticism

Al Qaeda leader Osama bin Laden claimed responsibility for the Christmas Day attempt to blow up an American civilian jet in an audiotape broadcast today on Arab television. U.S. intelligence officials quickly raised doubts about Bin Laden's role and suggested the statement was an attempt to score propaganda points for a plot already claimed by an increasingly independent faction of his movement in Yemen.

In the clip, Bin Laden said his group was behind the failed attempt allegedly carried out by Nigerian national Umar Farouk Abdulmutallab to blow up a Detroit-bound Northwest Airlines flight. Speaking directly to President Obama, the Al Qaeda leader vowed to continue launching terrorist attacks against the United States as long as Washington supported what he described as Israel's unjust treatment of Palestinians.

U.S. intelligence officials today did not cast doubt on the authenticity of the tape. But they expressed skepticism that Bin Laden or his lieutenants, believed to be based in Pakistan, played a meaningful role in conceiving or executing the Christmas Day plot.
