8. Jamaat Ansar al-Sunna Founded in September 2003, this Iraqi guerrilla force opposes the government led by Nouri al-Maliki as well as the forces of United States in Iraq. Led by Abu Abdullah al-Shafi'i and Mullah Krekar, this terrorist group is grounded in central and northern Iraq and is said to be linked with several Islamic organizations operating in Iraq. However, intelligence agencies of the Iraqi interim government and United States linked this group to al-Qaeda but later it was revealed that there is a wild conflict between these two terrorist groups.
