Red Zone was a term in use during the occupation of Iraq designating unsafe areas in Iraq after the 2003 invasion by the United States, United Kingdom, and other allies. It is contrasted with the high-security sector of Baghdad called the Green Zone. Since the Green Zone is a very small area, "Red Zone" is applied to the rest of Baghdad.
U.S. journalist Steven Vincent, who was murdered in Basra in August 2005, published a book titled In the Red Zone: A Journey into the Soul of Iraq ; it was based on his blog by the same title.[1]
