Ziad Khalaf Raja al-Karbouly was arrested by Jordanian intelligence forces last spring.
Officials say Karbouly confessed to his role in the terror cell and provided crucial information on the names of Zarqawi commanders and locations of their safe houses.Karbouly also admitted to his role in the kidnappings of two Moroccan embassy employees, four Iraqi National Guards and an Iraqi finance ministry official.
In a videotaped confession, Karbouly said he acted on direct orders from Zarqawi.
Officials say he will not be eligible for any of the $25 million reward money.
As Brian Ross reported this morning, the super-secret Task Force 145 does deserve the recognition for Wednesday's capture.
By the time two American jet fighters were called in to drop their 500 pound bombs, General George Casey was certain Zarqawi was in the house, and there was no thought of trying to capture him alive.
"Because the only means that could be applied in a timely fashion was the attack by air power and that was decided by General Casey as the right thing to do," U.S. Ambassador to Iraq Zalmay Khalilzad told ABC News.
The FBI on-line reward poster, offering a $25 million dollar bounty, today lists Zarqawi as deceased.
While Zarqawi's al Qaeda group has been decimated, it is only one of 14 major insurgent groups operating in Iraq.
"Different groups that operate independently and are not controlled by al Zarqawi, they don't need him, and they will continue their attacks in the long term," said Sajjan Gohel, an International Security Expert at the Asia-Pacific Foundation.
Authorities this morning are bracing for retaliatory attacks, and all vehicular traffic is banned in Baghdad and Baqubah, near the place where Zarqawi was finally tracked down.
