Армия Махди
In mid-October, a roadside bomb killed Qassim al-Tamimi, the chief of investigations for the provincial police force and a member of the rival Badr Organization. Badr fighters blamed the Mahdi Army for the killing and in response to this, the police captured a brother of the suspected bomber, who was a member of the Mahdi Army. Fighting began on October 17, when 800 masked members of the Mahdi army stormed three police stations in Amarah. Several firefights occurred between the militia and police over the course of the next four days.
