Iraqi security forces are composed of forces serving under the Ministry of Interior (which controls the Police and Popular Mobilization Forces) and the Ministry of Defense, as well as the Iraqi Counter Terrorism Bureau, reporting directly to the Prime Minister of Iraq, which oversees the Iraqi Special Operations Forces. Ministry of Defense forces include the Iraqi Army, the Iraqi Air Force and the Iraqi Navy. The Peshmerga are a separate armed force loyal to the Kurdistan Regional Government. The regional government and the central government disagree as to whether they are under Baghdad's authority and to what extent.
