CIA: Al-Zarqawi beheaded Berg in Iraq: "Intelligence officials conducted a technical analysis of the video released on an Islamic Web site and determined 'with high probability' that the person shown speaking on the tape - wearing a head scarf and a ski mask - is al-Zarqawi, a CIA official said, speaking on the condition of anonymity.
The speaker - determined to be al-Zarqawi - is then shown on the video decapitating American citizen Nicholas Berg, the official said."
