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.
Humanitarian crises of the Iraq War
Although Christians represent less than 5% of the total Iraqi population, they make up 40% of the refugees now living in nearby countries, according to U.N. High Commissioner for Refugees. UNHCR estimates that Christians comprise 24% of Iraqis currently seeking asylum in Syria. The census in 1987 counted 1.4 million Christians, however since the 2003 invasion radicalized Iraqi culture, the total number of Christians dropped to about 500,000, half of which live in Baghdad.
