Bush asserted that the bombing had been carried out by Al-Qaeda in Iraq, which denied involvement in the attack.

The Al-Askari Shrine, also known as the 'Askariyya Shrine and the Al-Askari Mosque, is a Twelver Shi'ite mosque and mausoleum, located in the city of Samarra, in the Saladin Governorate of Iraq.

Samarra is a city in Iraq. It stands on the east bank of the Tigris in the Saladin Governorate, 125 kilometers (78 mi) north of Baghdad. The modern city of Samarra was founded in 836 by the Abbasid caliph al-Mu'tasim as a new administrative capital and military base. In 2003 the city had an estimated population of 348,700. During the Iraqi Civil War (2006–08), Samarra was in the "Sunni Triangle" of resistance.

Shia Islam is the second-largest branch of Islam. It holds that Muhammad designated Ali ibn Abi Talib as both his political successor (caliph) and as the spiritual leader of the Muslim community (imam). However, his right is understood to have been usurped by a number of Muhammad's companions at the meeting of Saqifa, during which they appointed Abu Bakr as caliph instead. As such, Sunni Muslims believe Abu Bakr, Umar, Uthman and Ali to be 'rightly-guided caliphs', whereas Shia Muslims regard only Ali as the legitimate successor.
