Stealing the Enemy's Urban Advantage: The Battle of Sadr City - Modern War Institute

"n late 2006, Thawra District—Sadr City, and two, smaller, adjacent areas—saw fierce cycles of attacks and retaliations between Sunni and Shiite groups. Both sides attacked civilians, Iraqi security forces (ISF), and US troops. AQI frequently employed vehicle-borne improvised explosive devices (VBIEDs) and other mass-casualty attacks that had strategic implications on perceptions of the war in Iraq. The bodies of victims of sectarian murders were found dumped in the streets daily, averaging 200–250 per month."
