behalf, although no body was recovered and positively identified. Iraqi leaders denied the presence of Zarqawi in Fallujah prior to the U.S. attack on that city in November 2004. Zarqawi's existence was even questioned. Involvement of Zarqawi in significant terrorist incidents was not usually proven, although his group often claimed it perpetrated bombings.

She continued by stating; "But as I saw in coming weeks, Zarqawi remained the insurgents' hero, and the most influential member of their council, whatever Nour/Rashid's position...
