An Internet claim says the new leader of al-Qaida-in-Iraq personally "slaughtered" two American soldiers.
The exact wording suggests the men were beheaded.
The claim's authenticity could not be confirmed. If true, it's the first act of violence attributed to Abu Musab al-Zarqawi's successor.
The claim could also be an effort to bolster the image of Abu Hamza al-Muhajer, who was tapped to lead insurgents after al-Zarqawi was killed by a U-S airstrike. Al-Zarqawi was called the "slaughtering sheik" for the photos and videos of brutal slayings that circulated on the Internet and in media reports.
Major General William Caldwell says the military thinks it's found the remains of the two missing soldiers.
An Iraqi military official said it looked as if the victims were tortured and killed in a barbaric way.
