These guys in the picture that you posted are Feedaeyeen Saddam and they are Iraqis. The document that I translated talk about non Iraqi Arabs terorrists and how to train them and use them as suicide bombers. The document call them Feedaeyeen Arabs and in between parentheses (Estshaddeyen) i.e (Suicide martyrs). The document shows a great proof of Saddam Regime training and supporting the non Iraqi Arab terrorists who have been killing the Iraqis for the last three years.
But they are wearing the suicide belts and I thought Feedaeyeen Saddam didn't. I wouldn't rely on NBC knowing who these guys might really be.
