The civil war in Iraq and the success of a radical Islamist group which splintered from Al Qaeda in taking over central cities has focused global attention on the Shiite and Sunni militias that are spilling each other's blood there.

The Arabic newspaper Al Arabi al Jadid has provided its readers with a list of the armed militias operating in Iraq.

Sunni Islamic militias:

The Military Council of the Tribes in Iraq, in which 78 Sunni tribes are represented.

The Islamic State of Iraq and the Levant (ISIS) – a radical Salafist organization which broke off of Al Qaeda amid a power struggle with Al Qaeda's central leadership over involvement in the Syrian civil war. It is estimated to include some 15 to 22 thousand fighters, including thousands of foreign fighters, although precise figures are hard to come by and some have claimed the number could be higher. ISIS is leading the takeover in northern Iraq by Sunni militias, and is also rumored to include "thousands" of suicide bombers among its ranks.

Supporters of Islam (Ansar al-Islam) – a Salafist group that is identified with Al Qaeda. Headed by the Kurdish-Iraqi religious figure Mullah Krekar.
