Among the most shocking features of the recent torture report released by the United States Senate, one horrific manner of torment has gathered more attention that the rest shown in the report, all over the world: rectal feeding CIA.

While the parliamentary section of the United States government discusses whether or not it was right to release the report to the general public (with the GOP stating that transparency in this case sends the wrong message to outside enemies), the rectal feeding CIA practice has become infamous across the globe, as many have pointed out the human rights violations and even technical ineffectiveness of such a method.

According to The Guardian, the rectal feeding CIA has been sponsoring ever since the September 11 2001 attacks on Manhattan's World Trade Center twin towers was something of a secret before the release of this new report. While other practices had been widely reported in the past, this has shed some light in the way things have been dealt with ever in the realm of basic human rights for prisoners of war since 9/11.

According to CNN, some of the most shocking details regarding the torture report were those involving rectal feeding CIA or rectal rehydration.

"At least five CIA detainees were subjected to 'rectal rehydration' or rectal feeding without documented medical necessity," said the report, then specifying, "Majid Khan's 'lunch tray' of hummus, pasta with sauce, nuts and raisins was 'pureed' and rectally infused."

This practice is hardly an invention of the U.S. Central Intelligence Agency, as it's been used as far back as Ancient Greece - and, according to The Daily Mail, most recently in 19th century medicine. Before intravenous feeding was popularized, doctors went through this process when patients weren't able to eat and had to be fed this way.

Besides rectal feeding, the CIA torture report includes horrific interrogation methods such as mock executions, waterboarding, sleep deprivation and isolation in total darkness.
