Al Qaeda is warning that the U.S. has committed a "big mistake" and a "serious sin" in killing Osama bin Laden and is calling on Muslims to avenge his death.
In a statement posted on the Internet, al Qaeda's official online media organization, al-Fajr, says the American people "will pay the price" for the May 2 raid that killed bin Laden at a compound in Pakistan. It acknowledges that President Barack Obama "is protected by armies," but asks Americans, "who will protect you from our assault?" (AP)
