The first book published by a longtime Guantanamo Bay inmate that describes torture, humiliation and despair during 13 years in captivity was selling briskly in the United States on Wednesday and drawing hard-won attention to his case.

Mohamedou Ould Slahi's account from the U.S. naval base in Cuba, "Guantanamo Diary," was published on Tuesday after a seven-year legal battle.

It recounts ice baths, degradation and myriad humiliations in a first-person telling of his interrogation during the American war on terrorism from a prisoner who has never been charged by the United States with a crime and was ordered released by a U.S. federal court in 2010. That order was later vacated and Slahi, 44, has continued to be held.
