“The Pentagon sent a US veteran of the ‘dirty wars’ in Central America to oversee sectarian police commando units in Iraq that set up secret detention and torture centres to get information from insurgents,” The Guardian reports. “These units conducted some of the worst acts of torture during the US occupation and accelerated the country’s descent into full-scale civil war.”

After a 15-month investigation, The Guardian and the BBC Arabic has published its findings about the torture and atrocities organized and committed by US officials reporting directly to the highest echelons of the US government, including General David Petraeus.

“I remember a 14-year-old who was tied to one of the library’s columns,” said General Muntadher al-Samari, one of the Bush administration’s Iraqi proxies who helped run the torture centers. “And he was tied up, with his legs above his head. Tied up. His whole body was blue because of the impact of the cables with which he had been beaten.”

The report was “sparked by the release of classified US military logs on WikiLeaks that detailed hundreds of incidents where US soldiers came across tortured detainees in a network of detention centers run by the police commandos across Iraq.”

Antiwar.com reported on some of those leaks at the time: On May 30, 2006, the WikiLeaks releases revealed, “a joint US-Iraqi inspection” of an Iraqi detention facility “discovered more than 1,400 detainees in squalid, cramped conditions,” many of whom were illegally detained. Prisoners “displayed bruising, broken bones, and lash-marks, many claimed to have been hung by handcuffs from a hook in the ceiling and beaten on the soles of their feet and their buttocks.”

The inspectors found a torture contraption where ”a hook…on the ceiling of an empty room at the facility” was “attached [to] a chain-and-pulley system ordinarily used for lifting vehicles” and that “apparent bloodspots stained the floor underneath.” All 41 prisoners interviewed by US inspectors had reported being tortured and 37 juveniles were held illegally.

Rape and sexual abuse, primarily of young teenagers, was also widespread. “A number of juvenile detainees,” reads the cable, “alleged…that interrogators had used threats and acts of anal rape to induce confessions and had forced juveniles to fellate them during interrogations.”

Other instances of close cooperation between the US and abusive Iraqi forces in the MOI have been previously uncovered and the Iraq War Logs published by WikiLeaks revealed a secret US military order to ignore cases of torture and abuse by Iraqi interrogators.

The Guardian has compiled their findings into a 50-minute documentary which can be viewed here.
