The images included in the newly released report depict Zubaydah, an alleged al Qaeda operative who was captured in 2002 in Pakistan and put into CIA custody, in distress, either naked or lightly clothed, often forced into contorted positions, confined to tight spaces, or with his arms shackled above his head.

In a statement, Denbeaux said, "with this report, he is silent no more."

One drawing depicts a technique described in the report as "walling." In it, Zubaydah appears to be standing naked and shackled, while another man, whose face is hidden, appears to be holding something around Zubaydah's neck and slamming Zubaydah's head into a wall.

The CIA declined to comment on the newly released material.

The report quotes Zubaydah describing one of his walling sessions: "I fell down on the floor with each banging. I felt for few instants that I was unable to see anything, let alone the short chains that prevented me from standing tall. And every time I fell he would drag me with the towel which caused bleeding on my neck."

Other illustrations depict Zubaydah in what the report calls "stress positions," both standing and sitting, allegedly to create "physical pressure."

Another drawing depicts what the report refers to as "wall standing," showing Zubaydah with his arms shackled above his head as he stands on his toes, "to induce extreme pain, sleep deprivation, and mental anguish when used to extremes." The report quotes Zubaydah saying he "passed out" in that position, and felt his hands became "paralyzed or severed."

Several drawings depict Zubaydah confined to cramped boxes of various sizes, which the report quotes him as saying made him "scream unconsciously" from the pain from trying to keep his body contorted to fit in the box.

One illustration depicts Zubaydah undergoing the infamous water boarding technique, strapped to a table with water pouring on a cloth over his face, in order to simulate drowning, according to the report, which quotes Zubaydah as saying, "I felt I was going to die from drowning."
