Abu Omar al-Baghdadi

Hamid Dawud Mohamed Khalil al-Zawi (Arabic: حَمِيدُ دَاوُدَ مُحَمَّدُ خَلِيلِ ٱلزَّاوِيِّ, romanized: Ḥamīd Dāwud Muḥammad Ḵalīl az-Zāwī; 1959 – 18 April 2010), known as Abu Hamza al-Baghdadi and Abu Omar al-Qurashi al-Baghdadi (/ˈɑːbuː ˈoʊmɑːr ɑːl bɑːɡˈdɑːdi/ (listen) AH-boo OH-mar ahl bahg-DAHD-ee), was the leader of the militant groups Mujahideen Shura Council, and its successor, the Islamic State of Iraq, which fought against US forces and their Iraqi allies in the Iraq War.

On 18 April 2010, al-Baghdadi was killed when a joint operation of US and Iraqi forces rocketed a safe house 10 kilometres (6 mi) southwest of Tikrit. ISI Minister of War Abu Ayyub al-Masri and al-Baghdadi's son were also killed in the attack and 16 others were arrested.

Vice President Joe Biden said that the killings were "potentially devastating" blows to the terror network there and proof that Iraqi security forces are gaining ground. On 25 April 2010, a four-page statement by the Islamic State of Iraq was posted on a militant website early Sunday confirmed the death of al-Masri and Al-Baghdadi, saying "After a long journey filled with sacrifices and fighting falsehood and its representatives, two knights have dismounted to join the group of martyrs," the statement said. "We announce that the Muslim nation has lost two of the leaders of jihad, and two of its men, who are only known as heroes on the path of jihad." The ISI sharia minister, Abu al-Walid Abd al-Wahhab al-Mashadani, said the two leaders were attending a meeting when enemy forces engaged them in battle and launched an airstrike on their location.

The detainee identified as Khaled al-Mashhadani, a self-proclaimed intermediary to Osama bin Laden, claimed that al-Baghdadi was a fictional character created to give an Iraqi face to a foreign-run group. In March 2008, the spokesman for a rival insurgent organization, Hamas-Iraq, also claimed that al-Baghdadi was a fabrication made by Al-Qaeda to put an Iraqi face on their organization. However, US military officials later came to believe that the position of al-Baghdadi had been back-filled by an actual commander.

In July 2007, U.S. military spokesman Brigadier General Kevin Bergner, claimed that Abu Omar al-Baghdadi did not actually exist, and that all of his audio statements were actually read by an elderly Iraqi actor.

The Interior Ministry of Iraq claimed that al-Baghdadi was captured in Baghdad on 9 March 2007, but it was later said that the person in question was not him. On 3 May 2007, the Iraqi Interior Ministry said that al-Baghdadi had been killed by American and Iraqi forces north of Baghdad. On 23 April 2009, AFP reported that he had been arrested by the Iraqi military, and on 28 April the Iraqi government produced photos to prove it to skeptics. The claim was denied by the Islamic State in Iraq which according to SITE Institute released a recording of al-Baghdadi denying the government's claims. The Iraqi government continued to insist that the man captured was indeed Baghdadi, however tapes and messages from Baghdadi were released throughout 2009 and 2010.

Following the 2003 invasion of Iraq by the United States, he formed his own small insurgent group and took part in the Iraqi insurgency.

Abu Omar was born Hamid Dawud Muhammad Khalil al-Zawi in 1959 in the village of Al-Zawiyah, close to Haditha in Al-Anbar Governorate. He descended from the Qurayshi Al-Arajiyah. He graduated from the Police Academy in Baghdad and served as a police officer in Haditha. In 1993, he was dismissed from the police for Salafist ideology. After leaving the police, he worked at an electronics repair shop and served as the imam of the al-Asaf mosque.
