Shia–Sunni relations
Shia–Sunni discord in Iraq starts with disagreement over the relative population of the two groups. According to most sources, including the CIA's "World Factbook", the majority of Iraqis are Shia Arab Muslims (60%-70%), and Sunni Arab Muslims represent between 32% and 37% of the population. However, Sunni are split ethnically among Arabs, Kurds and Turkmen. Many Sunnis hotly dispute their minority status, including ex-Iraqi Ambassador Faruq Ziada, and many believe Shia majority is "a myth spread by America". One Sunni belief shared by Jordan's King Abdullah as well as his then Defense Minister Shaalan is that Shia numbers in Iraq were inflated by Iranian Shias crossing the border. Shia scholar Vali Nasr believes the election turnout in summer and December 2005 confirmed a strong Shia majority in Iraq.
Genocide of Shias by ISIL
Amnesty International has held ISIL responsible for the ethnic cleansing of ethnic and religious minority groups in northern Iraq (Christians and Izadis/Yazidis) on a "historic scale", putting entire communities "at risk of being wiped off the map of Iraq". In a special report released on 2 September 2014, it described how ISIL had "systematically targeted non-Sunni Muslim communities, killing or abducting hundreds, possibly thousands, of individuals and forcing more than tens of thousands of Shias, Sunni along with other minorities to flee the areas it has captured since 10 June 2014". The most targeted Shia groups in Nineveh were Shia Turkmens and Shabak, who have lived together for centuries in Nineveh province, large parts of which have come under ISIL's control.
