Ibrahim Sulieman Adnan Harun

Ibrahim Suleiman Adnan Adam Harun, also known as Spin Ghul, is a Saudi-born citizen of Niger who was convicted for his role in the death of two U.S. soldiers in 2003. In Italy, the government conducted three days of audio-recorded interviews in the presence of an Italian judge and defense counsel.

There was concern over Harun's sanity, but experts in mental health testified that he had the basic mental competency to stand trial. Nevertheless, he is reported to have insisted he was a "warrior", and tried to insist he should be tried in the Guantanamo military commission system. As of 2026, Harun is serving his life sentence at ADX Florence, a federal supermax prison near Florence, Colorado.

Law Professor Karen Greenberg, the author of several books on Guantanamo, described Harun's case as significant, as it showed how trials in civilian courts could be successful, in contrast to the long delays, and confusion, when suspects were tried, in Guantanamo military commissions.
