Iraqi civil war (2006–2008)

Middle Eastern Conflict 2006 2009
the civil war that started in 2006

The Iraqi civil war was an armed conflict from 2006 to 2008 between various sectarian Shia and Sunni armed groups, such as the Islamic State of Iraq and the Mahdi Army, in addition to the Iraqi government alongside American led coalition forces. In February 2006, the insurgency against the coalition and government escalated into a sectarian civil war after the bombing of Al Askari Shrine, considered a holy site in Twelver Shi'ism. US President George W. Bush and Iraqi officials accused Al Qaeda in Iraq (AQI) of orchestrating the bombing. AQI publicly denied any links. The incident set off a wave of attacks on Sunni civilians by Shia militants, followed by attacks on Shia civilians by Sunni militants. The UN Secretary General stated in September 2006 that if patterns of discord and violence continued, the Iraqi state was in danger of breaking up. On 10 January 2007, Bush said that "80% of Iraq's sectarian violence occurs within 30 mile (48 km) of the capital. This violence is splitting Baghdad into sectarian enclaves, and shakes the confidence of all Iraqis." By late 2007, the National Intelligence Estimate described the conflict as having elements of a civil war. In 2008, during the Sunni Awakening and the U. S. troop surge, violence declined dramatically. However, an insurgency by ISI continued to plague Iraq following the U. S. withdrawal in late 2011. In June 2014, the Islamic State of Iraq and the Levant, the successor to Islamic State of Iraq, launched a major military offensive against the Iraq government and declared a self proclaimed worldwide Islamic caliphate. This led to another full scale war from 2013 to 2017, in which the government declared victory. In October 2006, the Office of the United Nations High Commissioner for Refugees (UNHCR) and the Iraqi government estimated that more than 370,000 Iraqis had been displaced since 2006, bringing the total number of Iraqi refugees to more than 1.6 million. By 2008, the UNHCR raised the estimate to about 4.7 million (~16% of the population). The number estimated abroad was 2 million (a number close to CIA projections) and the number of internally displaced people was 2.7 million. The Red Cross stated in 2008 that Iraq's humanitarian situation was among the most critical in the world, with millions of Iraqis forced to rely on insufficient and poor quality water sources. According to the Failed States Index, produced by Foreign Policy and the Fund for Peace, Iraq was one of the world's top 5 unstable states from 2005 to 2008.

A multitude of groups formed the Iraqi insurgency, which arose in a piecemeal fashion as a reaction to local events, notably the realisation of the U. S. military's inability to control Iraq. Beginning in 2005 the insurgent forces coalesced around several main factions, including the Islamic Army in Iraq and Ansar al Sunna. Religious justification was used to support the political actions of these groups, as well as a marked adherence to Salafism, branding those against the jihad as non believers. This approach played a role in the rise of sectarian violence. The U. S. military also believed that between 5 and 10% of insurgent forces were non Iraqi Arabs. Independent Shi'a militias identified themselves around sectarian ideology and possessed various levels of influence and power. Some militias were founded in exile and returned to Iraq only after the toppling of Saddam Hussein, such as the Badr Organization. Others were created since the state collapse, the largest and most uniform of which was the Mahdi Army established by Muqtada al Sadr and believed to have around 50,000 fighters. By the end of 2008, where the civil war had ended, there was evidence of a decrease in civilian casualties, and likewise in ethno sectarian casualties. The commanding general of the Multi National Force Iraq (MNF I), Raymond Odierno, testified before the House Armed Services Committee in September 2009 that overall attacks had decreased 85% in the last two years from 4064 in August 2007 to 594 in August. 2009: with 563 attacks in September (through September 28).

Bomb attacks aimed at civilians usually targeted crowded places such as marketplaces and mosques in Shi'a cities and districts. The bombings, which were sometimes co ordinated, often inflicted extreme casualties. For example, the 23 November 2006 Sadr City bombings killed at least 215 people and injured hundreds more in the Sadr City district of Baghdad, sparking reprisal attacks, and the 3 February 2007 Baghdad market bombing killed at least 135 and injured more than 300. The co ordinated 2 March 2004 Iraq Ashura bombings (including car bombs, suicide bombers and mortar, grenade and rocket attacks) killed at least 178 people and injured at least 500.

Since August 2003, suicide car bombs were increasingly used as weapons by Sunni militants, primarily al Qaeda extremists. The car bombs, known in the military as vehicle borne improvised explosive devices (VBIEDs), emerged as one of the militants' most effective weapons, directed not only against civilian targets but also against Iraqi police stations and recruiting centers. These vehicle IEDs were often driven by the extremists from foreign Muslim countries with a history of militancy, such as Saudi Arabia, Algeria, Egypt, and Pakistan. Multiple suicide bombings had roughly the same target distribution as single blasts: about three quarters of single and multiple blasts were sent against Iraqi targets.

Death squad style killings in Iraq took place in a variety of ways. Kidnapping, followed by often extreme torture (such as drilling holes in people's feet with drills) and execution style killings, sometimes public (in some cases, beheadings), emerged as another tactic. In some cases, tapes of the execution were distributed for propaganda purposes. The bodies were usually dumped on a roadside or in other places, several at a time. There were also several relatively large scale massacres, like the Hay al Jihad massacre in which some 40 Sunnis were killed in a response to the car bombing which killed a dozen Shi'a. The death squads were often disgruntled Shi'a, including members of the security forces, who killed Sunnis in revenge attacks they blamed the insurgency against the Shi'a dominated government. Allegations of the existence of the death squads, made up of Shiites, and their role in executions of Sunnis, began to be promulgated when Bayan Jabr took over the Interior Ministry, although there was no exact proof. On top of that the Badr Brigade, a military wing of the pro Iranian Supreme Council of the Islamic Revolution in Iraq, was accused of being behind the killings. Iraq Body Count project data shows that 33% of civilian deaths during the Iraq War resulted from execution after abduction or capture. These were overwhelmingly carried out by unknown actors including insurgents, sectarian militias and criminals. Such killings occurred much more frequently during the 2006–07 period of sectarian violence.

On 22 February 2006, a highly provocative explosion took place at the al Askari Mosque in the Iraqi city of Samarra, one of the holiest sites in Shi'a Islam, believed to have been caused by a bomb planted by al Qaeda in Iraq. With the explicit strategic goal of triggering a "sectarian war", Al Zarqawi hoped that through such a sectarian conflict he could rally Iraq's Sunnis behind a common cause against the Shiite dominated government in Baghdad and the U. S. occupation. Although no injuries occurred in the blast, the mosque was severely damaged and the bombing resulted in violence over the following days. Over 100 dead bodies with bullet holes were found the next day, and at least 165 people are thought to have been killed. In the aftermath of this attack the U. S. military calculated that the average homicide rate in Baghdad tripled from 11 to 33 deaths per day. In several cases, Christian churches were also attacked by the extremists. Later, another al Askari bombing took place in June 2007. Iraq's Christian minority also became a target by Al Qaeda Sunnis because of conflicting theological ideas.

Some Iraqi service members deserted the military or the police and others refused to serve in hostile areas. For example, some members of one sect refused to serve in neighborhoods dominated by other sects. The deserting soldiers left behind weapons, uniforms and warehouses full of heavy weaponry. Before the fall of Mosul, the ISF was losing 300 soldiers a day to desertions and deaths.

By 2008, the UNHCR raised the estimate of refugees to a total of about 4.7 million, with 2 million displaced internally and 2.7 million displaced externally. Roughly 40% of Iraq's middle class is believed to have fled, the U. N. said. Most were fleeing systematic persecution and had no desire to return. Refugees were mired in poverty as they were generally barred from working in their host countries. A 25 May 2007 article noted that in the past seven months only 69 people from Iraq had been granted refugee status in the United States.
