Khuzestan Province is a petroleum-rich, ethnically-diverse province in southwestern Iran. Oil fields in the province include Ahvaz Field, Marun, Aghajari, Karanj, Shadegan and Mansouri. Amnesty International has voiced human-rights concerns about Khuzestan's Arab population, and United Nations special rapporteur Miloon Kothari has also drawn attention to Arab displacement and poverty among the Laks.
