The military began using the restraint chair at Guantanamo to feed prisoners in January 2006 after hunger strikers grew dangerously thin and officials feared some might die.
Then, as now, prisoners said they were striking over what they considered the reckless handling of their Korans by prison staff, conditions at the detention center and their indefinite confinement.
The military insists all its procedures are humane.
However, Zuhair, and others, have long maintained otherwise.
“During each force-feeding, my nose bleeds,” he said in a sworn statement submitted to the court by Kassem. “The pain from each force-feeding is so excruciating that I am unable to sleep at night because of the pain in my throat.”
