Over the weekend, news reports revealed that terror suspects are being held in a secret part of the prison at that Bagram air base for interrogation. They’re denied access to the International Committee of the Red Cross, and some have claimed they’ve been subjected to abuses, including sleep deprivation, sexual humiliation and other maltreatment similar to the sorts of interrogation abuses that occurred during the Bush administration.

Human Rights First is now calling for a full investigation of the so-called “black prison” at Bagram and the alleged abuses there.

“These allegations raise serious questions about whether reforms initiated by the Obama administration are being properly implemented and about whether they are sufficient to end torture and detainee abuse,” the organization wrote in a letter sent yesterday to Afghanistan Commander Vice-Admiral Robert Harward. “If substantiated, the alleged conduct of detaining authorities is in violation of U.S. law, including the Detainee Treatment Act, and the 2006 Army Field Manual, which is applicable to all U.S. government agencies. It is also in violation of international law, including Common Article 3 of the Geneva Conventions, the International Covenant on Civil and Political Rights, and the Convention against Torture.”

The letter asks that the results of the investigation be made public and that the perpetrators of abuses be held accountable.

Ramzi bin al Shibh is one of five men charged by the U.S. military commission with having participated in planning the Sept. 11 hijacking and suicide mission. His lawyers say he’s not competent to represent himself or to stand trial because he suffers from “delusional disorder” and hallucinations, and he is being treated with psychotropic drugs by Guantanamo Bay prison doctors.

To prepare his defense, his lawyers tried to get evidence from the government about which specific interrogation techniques were used on him, and how frequently. Waterboarding, stress positions, sleep deprivation and sexual humiliation are among the techniques to which the the alleged 9/11  conspirators were subjected, according to the so-called Office of Legal Counsel “torture memos” released earlier this year.

But the military judge hearing the case, Army Col. Stephen Henley, ruled on Aug. 6 that “evidence of specific techniques employed by various governmental agencies to interrogate the accused is … not essential to a fair resolution of the incompetence determination hearing in this case.” The government had argued that releasing the evidence would endanger national security.

The Miami Herald obtained a copy of the ruling on Monday.
