The Guardian of London is reporting that on the day after the so-called handover of power in Iraq, the U.S. military police raided a detention center being operated by the Iraqi ministry of the interior in Baghdad. At one point, the U.S. threatened to free all of the Iraqi prisoners. The incident raised new questions as to how much sovereignty the new Iraqi government actually has. The U.S. said they carried out the raid because they had received reports that Iraqi interrogators were physically abusing the detainees. The 150 prisoners had all been picked up in what was described as the first Iraqi-led anti-crime and anti-terrorism operation.
