In 2004, Sunni militants bombed churches and kidnapped Christians in the Baghdad district of Dora. The US military briefly 'cleared' Dora in autumn 2006, but militants tied to Al Qaeda in Iraq reestablished themselves in Dora in late 2006 and began harassing Christians. By January 2007, ISI proclamations appeared on walls in Dora and leaflets were circulated: women should wear veils; shorts and cellphones were prohibited. Christians were given the choice: either pay a tax, or become a Muslim, or leave the district. By May 2007, 500 Christian families had left Dora. ISI also targeted Christians in the 2010 Baghdad church massacre.For continued persecution of (Christian) Assyrians in 2014 by ISIL, see: Persecution of Assyrians by ISIL.
