Buried in a very good story about sectarian violence and the breakdown of civil society in Baghdad, the London Times scored itself a little scoop. It publishes a (really cool) U.S. military map deconstructing Baghdad by ethnic neighborhoods and degree of danger.
The US military has drawn up a new map of Baghdad to reflect its ethno-sectarian fault lines. Published here for the first time, it lists the mixed neighbourhoods considered to be most explosive. Four of the five are on the western bank of the Tigris, called Karkh, where mixed neighbourhoods are still prevalent. Predominently Shia Kadhamiya and the largely Sunni areas of Qadisiya, Amariya and Ghazaliya have become the deadliest battlegrounds, according to US forces.
Also interesting is that part of the Green Zone seems to be under Sunni control.
