Iran has been actively involved in supporting Shi'a militias and encouraging sectarian violence in Iraq since the invasion of 2003.
Although one of the smallest factions in the Sunni insurgency, Al-Qaeda in Iraq may be one of the most deadly. US operations have put tremendous pressure on the group.
Phantom Strike, a series of targeted joint operations against al Qaeda, Sunni, and Shi'a insurgent elements
in Baghdad and the surrounding areas, was launched on August 13, 2007.
The 8th Iraqi Army Division (IAD), commanded by Major General Othman Farhood, is based ninety miles southeast of Baghdad in Diwaniyah.
