List of bombings during the Iraq War

Since the 2003 invasion of Iraq, bombings have killed thousands, including forces of U.S-led coalition, officials of Iraqi federal government and civilians. Suicide bombings have been used as a tactic in other armed struggles, but their frequency and lethality in Iraq is unprecedented. During the invasion, the United States and United Kingdom dropped 29,199 bombs. The article does not list these, but concentrates on the smaller number of insurgent bombings during the post-invasion phase of the Iraqi conflict (2003–present).

Most of the bombings were carried out by Sunni insurgents and Sunni Islamist organizations such as Jama'at al-Tawhid wal Jihad, Al-Qaeda in Iraq, Jama'at Ansar al-Sunna, and the Islamic State of Iraq. The main targets of the bombings were the forces of the U.S.-led coalition and those collaborating with it. The Islamic State of Iraq organization also targeted Shia civilians.

Perpetrators
A 2005 Human Rights Watch report analysed the insurgency in Iraq and highlighted, "The groups that are most responsible for the abuse, namely al-Qaeda in Iraq and its allies, Ansar al-Sunna and the Islamic State of Iraq, have all targeted civilians for abductions and executions. The first two groups have repeatedly boasted about massive car bombs and suicide bombs in mosques, markets, bus stations and other civilian areas. Such acts are war crimes and in some cases may constitute crimes against humanity, which are defined as serious crimes committed as part of a widespread or systematic attack against a civilian population."

Analysis
A 2008 RAND Research brief on counterinsurgency in Iraq: 2003 - 2006 depicts a chart that shows in June and July 2004, Iraqi insurgents began to shift their focus away from attacking U.S. and coalition forces with roadside bombs and instead began targeting the Iraqi population with suicide bombers and vehicle-borne IEDs. By increasing the number of suicide bombings against civilians and accepting their targeting in retribution, the insurgents sought to expose the weakness of the coalition-Iraqi security and reconstruction apparatus, threaten those who collaborated with the government, generate funds and propaganda, and increasingly enact sectarian revenge. The U.S. failure to adapt to this shift had dramatic consequences. By June 2004, U.S. deaths represented less than 10% of overall deaths on the battlefield and Iraqi deaths represented more than 90% - a figure that remained constant for the next 18 months of the War.

An analysis by Iraq Body Count and co-authors published in 2011 concluded that at least 12,284 civilians were killed in at least 1,003 suicide bombings in Iraq between 2003 and 2010. The study reveals that suicide bombings kill 60 times as many civilians as soldiers
