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.

Ansar al-Sunna stands for Supporters of Islam. "They are an militant Islamic Kurdish separatist movement seeking to transform Iraq into an Islamic state". This group has a Salafist worldview, which means that they insist on a puritanical form of Islam and they seek to emulate the practices of Muhammad. This movement was founded in 2001 by Mullah Krekarand they got financial and logistical help from al-Qaeda and Osama Bin laden. Some of the members of this organization transport money from Germany to northern Iraq to help finance the group.  "This group targets secular Iraqi Kurds-particularly members of the Patriotic Union of Kurdistan (PUK)".  Ansar was named a Foreign Terrorist Organization (FTO) by the U.S. Department of State on March 22, 2004. They are considered an active terrorist group in northern and central Iraq today. Ansar al-Islam operates primarily in northern and central Iraq and claims the second largest number of Sunni jihadist attacks in Iraq after Al-Qaeda. This organization is also known to behead their captives. The goal of Ansar-al Sunna is to have an Islamic country where its people are strong. There are a maximum of two thousand "hard fighters" in Ansar-al-Sunna. This group is the main threat in Northern Iraq right now. This group will most likely continue to attack the Kurds until the country has reached a decision on the position of the Kurds.
