BAGHDAD: The US army was handing over control of Camp Cropper prison to Iraqi authorities on Thursday, effectively ending one of the most controversial chapters of the American military occupation.
Cropper, west of Baghdad and holding 1,600 detainees, opened immediately after the US-led invasion of Iraq in March 2003.
It was built to handle senior members of Saddam Hussein’s toppled Baathist regime.
The dictator himself was its most famous inmate after his capture in November 2003 and eventual execution more than three years later.
An official transfer of authority ceremony involving US and Iraqi military officers was to take place around noon (0900 GMT).
More than 100,000 prisoners have passed through US custody in Iraq, where Camp Bucca near the southern city of Basra was closed in September 2009 and Camp Taji north of Baghdad shut earlier this year.
Among the last of Saddam’s inner circle to leave Camp Cropper was former deputy prime minister Tareq Aziz, who was transferred to Khadimiyah prison in Baghdad on Tuesday night.
Saddam’s former secretary Abed Hmoud, the former interior minister Mohammed Zumam and former oil minister Amir Mohammed Rashid, were among 25 other prisoners moved together with Aziz.
Cropper was originally a tented site but it was upgraded after the Abu Ghraib prison scandal in 2004 where photographs showed naked and hooded Iraqi prisoners being beaten and humiliated by their US guards.
Abu Ghraib, which was a notorious torture and execution centre during the Saddam era, was returned to Iraqi control last February.
General Ray Odierno, the commander of US forces in Iraq, told reporters on Tuesday that the handover of Camp Cropper had been planned for one year and a system of training and safeguards had been put in place.
He also said Cropper proved that the American military had learned lessons from Abu Ghraib, regarded as the nadir of the US occupation.
"Abu Ghraib is a lesson that we were not prepared to handle large masses of detainees when we came into this operation in 2003," Odierno said.
"We made some real errors in thinking it was going to be like Desert Storm and we would just hold prisoners of war for a period of time.
"We did not properly anticipate a counter-insurgency which would require us to handle a large number of detainees… in fact we were not trained and prepared to do it. And we ended up having significant issues," he added.
Despite Thursday’s handover around 200 high value detainees will stay under US control at Camp Cropper, Odierno and the Iraqi government has said.
