Washington, Sept 12: CIA analysts have concluded that a voice on a videotape aired this week by the al-Jazeera Television news station was "probably" that of al-Qaeda leader Osama bin Laden, a CIA official said today. The assessment came a day after the agency's analysts said they had "high confidence" that an audiotaped message on the tape attributed to al-Qaeda number two, Ayman Zawahiri was authentic. "After further analysis of the tape that aired on September 10, the CIA assesses that the voice is probably that of Osama bin Laden," the official said, speaking on condition of anonymity.
