In an interview with me last year, Gitmo psyche nurse Stashiu said:
There were a few detainees there who werent actually fighting against the Coalition, but they were fighting their own government and would have been executed if we returned them there. Since we are not allowed to ship someone where we have reason to believe they would face torture or death, they are stuck at GTMO until we can find a country to accept them without killing them. But they were combatants of some sort.
Looks like he was right:
An inmate of Guantanamo Bay who spends 22 hours each day in an isolation cell is fighting for the right to stay in the notorious internment camp.
Ahmed Belbacha fears that he will be tortured or killed if the United States goes ahead with plans to return him to his native Algeria.
