Jesus!

This is horrid.

A mob of gunmen went on a brazen daytime rampage through a predominantly Sunni Arab district of western Baghdad on Sunday, pulling people from their cars and homes and killing them in what officials and residents called a spasm of revenge by Shiite militias for the bombing of a Shiite mosque on Saturday. Hours later, two car bombs exploded beside a Shiite mosque in another Baghdad neighborhood in a deadly act of what appeared to be retaliation.

While Baghdad has been ravaged by Sunni-Shiite bloodletting in recent months, even by recent standards the violence here on Sunday was frightening, delivered with impunity by gun-wielding vigilantes on the street. In the culture of revenge that has seized Iraq, residents all over the city braced for an escalation in the cycle of retributive mayhem between the Shiites and Sunnis that has threatened to expand into civil war.

The violence coincided with an announcement by American military officials that they had formally accused four more American soldiers of rape and murder, and a fifth soldier of "dereliction of duty" for failing to report the crimes, in connection with the deaths of a teenage Iraqi girl and three members of her family.

The US has to get out of Iraq before one tribe takes control. One tribe may ultimately take control, but the US presence isn't helping matters.
