Housed in an old brick factory outside of Kabul's business district to the north of the city, the Salt Pit was considered by many to be the largest CIA prison in Afghanistan.
At least one prisoner is known to have died under torture in the Salt Pit in 2002.
A CIA case officer ordered guards to strip naked an uncooperative young Afghan detainee, chain him to the concrete floor and leave him there overnight without blankets.
According to the Washington Post, Afghan guards paid by the CIA and working under CIA supervision dragged the prisoner around the concrete floor of the facility, “bruising and scraping his skin” before placing him in a cell for the night without clothes.
An autopsy listed “hypothermia” as the cause of death, and the man was buried in an “unmarked, unacknowledged cemetery.”
A U.S. government official interviewed told the Post: “He just disappeared from the face of the earth.”
Khaled el-Masri confirmed: “Somebody in the prison told me that before I came somebody died under torture.”
The Salt Pit is no longer believed to be in operation.
