The American Civil Liberties Union (ACLU) says the intelligence agency has broken both US and international law.
It is acting for a man allegedly flown to a secret CIA prison in Afghanistan.
"The lawsuit will charge that CIA officials at the highest level violated US and universal human rights laws when they authorised agents to abduct an innocent man, detain him incommunicado, beat him, drug and transport him to a secret CIA prison in Afghanistan," the ACLU said in a news release.
CIA agents have broken ranks to reveal the ‘cruel and inhuman’ interrogation techniques they are ordered to use at secret prisons around the world, including freezing and near-drowning.
At least one death has been reported elsewhere, however. In a CIA facility in Kabul known as the "Salt Pit", an officer, described as young and inexperienced, used the "cold treatment" on a detainee, who was left outdoors, naked, throughout a freezing Afghan night. He died of hypothermia. The case is being investigated, along with several others in Afghanistan and Iraq where interrogators – CIA officers, civilian contractors or members of the special forces – went well beyond the guidelines and suspects died as a result.
Let’s make sure I have this right. The US went to war in Iraq because Saddam used torture, but it’s ok for the US to use torture because it hates the terrorists and loves freedom. But, don’t ask Condi about any of this during her current trip to Europe because she’ll tell you to shut up.
