| Abu Musab al-Zarqawi, whose group had taken three Westerners hostage in Iraq, was unlikely the speaker on a videotape showing the beheading of American Jack Hensley, a CIA official said on Thursday. "It's unlikely that the voice is that of Abu Musab al-Zarqawi," the official said after the CIA conducted a technical analysis of the tape. The CIA had said it had high confidence that Zarqawi was the speaker on another videotape posted earlier this week showing the beheading of another American hostage, Eugene Armstrong. Zarqawi's group is still holding a Briton, Kenneth Bigley. |
