A Koran is suspended by a surgical mask from the wall of a cell at Camp One. More than 1,600 Korans were issued to inmates between January 2002 and June 2005. The use of surgical masks to hold Korans enables inmates to keep the books off the floor, thus avoiding sacrilegious contamination. Alleged abuse of the Koran by guards and interrogators has led to several hunger strikes by prisoners. In June 2005, the U.S. Southern Command confirmed that five cases of Koran mistreatment had occurred over a period of two and a half years.
