In addition, the news agencies NBC and Reuters reported members of their own staff had been subjected to sexual and religious taunts and humiliation while in US custody in Iraq earlier this year. Two of the Reuters staff said they had been forced to insert a finger into their anus and then lick it, and were forced to put shoes in their mouths, which is particularly humiliating in Arab culture. The staffers and journalists were also warned they would be sent to Guantanamo Bay. Before the Abu Ghraib prison scandal emerged, the U.S. military said it conducted an internal investigation and found no evidence the NBC and Reuters staffers were mistreated.
