Mustafa Ait Idir (sometimes written as Ait Idr) is an individual formerly held in the United States Guantanamo Bay detainment camps, in Cuba.
Ait Idir was born in Algeria, but moved to Bosnia, married a Bosnian woman, and became a Bosnian citizen.
Idir was arrested on October 18, 2001, on suspicion of participating in a conspiracy to bomb the United States Embassy.
After their release following their acquittal, the six men were captured on January 17, 2002, by American forces, who transferred them to Guantanamo Bay.
Ait Idr has alleged brutal treatment there.
He claims that guards beat him when he was shackled, and bent back his fingers, breaking them.
(Idir has a black belt and was the Croatian martial arts champion.) During another alleged beating, guards threw him onto a gravel path, where one guard jumped on him, with his full weight, causing a stroke that left part of his face paralyzed.
On December 16, 2008, Ait Idir was one of three prisoners released to Bosnia after he was found innocent.
