At that time, the United States was throwing money at anyone who could deliver an out-of-town Arab found in the region. Nabil was sold to the United States for a bounty of $5,000 and taken to an underground prison in Kabul. There he experienced torture for the first time. To house the prisoners of its war on terror, the United States military put up a makeshift prison at Bagram Air Base in Afghanistan. Bagram would quickly become notorious, and make Guantánamo look like a church camp. When Nabil arrived there in January 2002, as one of the first prisoners, there were no walls, only razor-wire cages. In the bitter cold, Nabil was forced to sleep on concrete floors without cover. Food and water were scarce. To and from his frequent interrogations, Nabil was beaten by United States soldiers and dragged up and down concrete stairs. Other prisoners died. After a month in Bagram, Nabil was transferred to a prison at Kandahar, where the abuse continued.

Throughout his incarceration in Afghanistan, Nabil strenuously denied any connection to Al Qaeda, the Taliban or anyone or any organization remotely linked to the 9/11 attacks. And the Americans had no proof of his involvement, save for bogus claims implicating him from other prisoners extracted in a Kabul torture chamber. Several United States interrogators told him his was a case of mistaken identity. Nonetheless, the United States had adopted strict rules for Arabs in custody — all were to be sent to Guantánamo. On Feb. 15, 2002, Nabil was flown to Cuba; shackled, bound and hooded.

Since then, Nabil has been subjected to all the horrors of the Gitmo handbook: sleep deprivation, sensory deprivation, temperature extremes, prolonged isolation, lack of access to sunlight, almost no recreation and limited medical care. In 11 years, he has never been permitted a visit from a family member. For reasons known only to the men who run the prison, Nabil has never been waterboarded. His lawyer believes this is because he knows nothing and has nothing to give.

The United States government says otherwise. In documents, military prosecutors say that Nabil was staying at a guesthouse run by people with ties to Al Qaeda and that he was named by others as someone affiliated with terrorists. But Nabil has never been charged with a crime. Indeed, on two occasions he has been cleared for a “transfer,” or release. In 2007, a review board established by President George W. Bush recommended his release. Nothing happened. In 2009, another review board established by President Obama recommended his transfer. Nothing happened.

According to his guards, Nabil is a model prisoner. He keeps his head down and avoids trouble. He has perfected his English and insists on speaking the language with his British lawyers. He writes in flawless English. As much as possible, under rather dire circumstances, he has fought to preserve his physical health and mental stability.
