What happened

Detainees were forced to stand on broken limbs for hours, kept in complete darkness, deprived of sleep for up to 180 hours, sometimes standing, sometimes with their arms shackled above their heads.

 

Prisoners were subjected to “rectal feeding” without medical necessity. Rectal exams were conducted with “excessive force”. The report highlights one prisoner later diagnosed with anal fissures, chronic hemorrhoids and “symptomatic rectal prolapse”.

The report mentions mock executions, Russian roulette. US agents threatened to slit the throat of a detainee’s mother, sexually abuse another and threatened prisoners’ children. One prisoner died of hypothermia brought on in part by being forced to sit on a bare concrete floor without pants.

Note that the violence is sexualized in order to maximize the detainees’ humiliation and thus render them more compliant.
