According to CNN:
“The voice on the tape could not be verified as that of al-Zarqawi. CNN staff members familiar with al-Zarqawi’s voice said the voice on the tape did not sound like him.”
However – many in the news media and US generals are still stating that the executioner is al-Zarqawi. It would seem that those who are perpatrating this fraud wants very much to link it to al-Zarqawi.
“U.S. intelligence officials have concluded that terrorist leader Abu Musab al-Zarqawi was the person shown on a video beheading an American civilian in Iraq, based on an analysis of the voice on the video, a CIA official said Thursday.”
