Some 400,000 secret US military documents that detail abuse, summary executions and torture in Iraq have been placed in the public domain by Wikileaks.
The field reports allege that US authorities failed to investigate cases of rape, torture, and even murder carried out by Iraqi police and military.
The sheer number of reports of prisoner abuse points to a system where torture is a daily occurrence and, by and large, goes unpunished.
The files are believed to come from the same US intelligence analyst who leaked the 90,000 logs from the Afghan war, which so enraged the Pentagon.
The documents claim that the coalition has a policy of ignoring allegations against Iraqi security forces and simply pass the reports on to the units where the alleged abuse took place.
In sharp contrast allegations against British and US forces are subject to investigation.
