United Nations ? Sudan’s actions in Darfur have helped turn the region into “a crime scene,” the chief U.N. prosecutor charged Thursday, expanding on a scathing report this week that directly linked the government to a feared militia blamed for much of the killing.

“Despite promises and denials, over the last five years, millions of civilians have been targeted by officials who vowed to protect them. Impunity reigns,” International Criminal Court chief prosecutor Luis Moreno-Ocampo told a rapt Security Council.

In the report obtained earlier this week by The Associated Press, Moreno-Ocampo alleged that Sudan’s “whole state apparatus” is implicated in crimes against humanity in the country’s western Darfur region.

According to the report, Sudan during the past six months has not shown any increased cooperation with the court – as is required under international law set by the council – in securing the arrests of people indicted by the court for crimes against humanity in the country’s Darfur region.
