In Afghanistan, the prison at Bagram Air Base was initially housed in an abandoned brickmaking factory outside Kabul known as the "Salt Pit", but later moved to the base some time after a young Afghan died of hypothermia after being stripped naked and left chained to a floor. During this period, there were several incidents of torture and prisoner abuse, though they were related to non-secret prisoners, and not the CIA-operated portion of the prison. At some point prior to 2005, the prison was again relocated, this time to an unknown site. Metal containers at Bagram Air Base were reported to be black sites. Some Guantanamo Bay detainees report being tortured in a prison they called "the dark prison", also near Kabul. Also in Afghanistan, Jalalabad and Asadabad have been reported as suspected sites.
