In the past, American intelligence officials have said Mr. Zarqawi had lost a leg in an American bombing in Afghanistan and was fitted with a prosthetic leg in Iraq in 2002, during a stay in Baghdad that they have called evidence of tacit support by Saddam Hussein's government.
But the figure in the video shows no evidence of a limp. An American counterterrorism official said Thursday that while intelligence analysts still believed that Mr. Zarqawi inhad jured his leg and was treated in Iraq, they no longer thought that he had lost a limb.
And...
Some recent news media reports have suggested that the Arabic-language accent heard on the tape was not consistent with the part of Jordan where Mr. Zarqawi originated. A C.I.A. official would not say exactly how the agency had made its assessment, but indicated that the voice pattern and regional accent heard on the tape had both contributed to the assessment of a "high probability" that it was Mr. Zarqawi speaking.
I think most will agree that neither of these sources are exactly shills for the Bush Administration.
