Christian Lorentzen reviews Guantánamo Diary by Mohamedou Ould Slahi: In the autumn of 2001 Mohamedou Ould Slahi was working in Nouakchott, the capital of Mauritania, setting up computer networks. He was born in the hinterlands, son of a nomadic camel trader, and had picked up the trade in Germany; he went to the University of Duisberg on a scholarship in 1988, at the age of 17. He’d long been a fan of the German national football team. He was also devout and had memorised the Koran as a teenager. In 1991 he went to Afghanistan to train with the mujahedin and pledged an oath to al-Qaida. He made another trip the next year, but saw little action fighting Muhammad Najibullah’s communist government before it fell. When the fighting disintegrated into factional struggles, he went back to Germany. He tried once to join the war in Bosnia, but couldn’t get through Slovenia. He worked in Duisberg until 1999, when his visa expired and pressure was coming down from the immigration office. He applied for permanent residency in Canada and went to Montreal, where he led prayers at a mosque attended by an Algerian called Ahmed Ressam. On 14 December 1999, Ressam was arrested at the US border with explosives and timing devices in his rented car. This was the Millennium Plot to blow up Los Angeles International Airport, and though Ressam was a stranger to him it was the start of Slahi’s troubles.

In Montreal he believed he was being watched, possibly through a small hole drilled through his bedroom wall from his neighbour’s flat. (He called the police about it and they told him to fill the hole with caulk.) He was questioned by Canadian intelligence, but let go. Still, he was spooked, and in January 2000 he set off to return to Mauritania, via Dakar; on landing he was picked up by Senegalese special forces. He was rendered to Nouakchott, held for weeks, threatened with torture, and interrogated by Mauritanian intelligence and the FBI. Here was the start of the American authorities’ four-year fixation on two words, ‘tea’ and ‘sugar’, picked up on a tapped phone conversation and presumed to be code. They released him to return to his family. On his way out, the director of Mauritanian intelligence told him: ‘Those guys have no evidence whatsoever.’ [Continue reading…]
