The Iraqi Turkomans claim to be the third largest ethnic group in Iraq, residing almost exclusively in the north, in an arc of towns and villages stretching from Tel Afar, west of Mosul, through Mosul, Erbil, Altun Kopru, Kirkuk, Tuz Khurmatu, Kifri and Khaniqin. Before the war that began in March 2003, there were anything between 600,000 and 2 million Turkomans, the former figure being the conservative estimate of outside observers and the latter a Turkoman claim.
