Hamas of Iraq (Arabic: حماس العراق Ḥamās al-'Irāq) is a Sunni militia group based in Iraq, which split from the 1920 Revolution Brigade on 18 March 2007. The group claims to have released videos of its attack on US troops. The 1920 Revolution Brigade insists that Hamas in Iraq was involved in assisting US troops in their recent Diyala operations against Al-Qaeda in Iraq. Iraqi Prime Minister Nouri al-Maliki has feared the US-armed 'concerned local citizens' are an armed Sunni opposition in the making, and has argued that such groups should be under the command of the Iraqi Army or police. On October 11, 2007, the militia group joined a political council that embraced armed insurgency against American forces.
