When Mohammed el Gorani was a boy in Saudi Arabia, he found that he could not find good work or education because his family was from Chad. A friend from Pakistan offered to connect him with relatives there who would help him get educated. He took his work savings and flew to Pakistan, where he was kidnapped by local thugs and sold to the US Army as an Al Qaeda operative. He was tortured by the thugs, then tortured by the Army, then sent to Guantanamo for six years, where he was tortured further. He was eventually released and exonerated, but a confidential agreement between the government of Chad and the US State Department prohibits him from rejoining his family in Saudi Arabia. He suffers lasting health problems. Here is his story.

We landed at another airstrip. It was night. Americans shouted: 'Terrorists, criminals, we're going to kill you!' Two soldiers took me by my arms and started running. My legs were dragging on the ground. They were laughing, telling me: 'Fucking nigger!' I didn't know what that meant, I learned it later. They took off my mask and I saw many tents on the airstrip. They put me inside one. There was an Egyptian (I recognised his Arabic) wearing a US uniform. He started by asking me: 'When was the last time you saw Osama bin Laden?' 'Who?' He took me by my shirt collar and they beat me again. During all my time at Kandahar, I was beaten. Once it was like a movie – they came inside the tent with guns, shouting: WE CAUGHT THE TERRORISTS! And they put us in handcuffs. 'Here are their guns!' And they threw some Kalashnikovs onto the ground. 'We've been fighting them, they killed a lot of people!' All that was for cameras, which were held by men in uniforms. I was lying on the ground with the other prisoners. They brought dogs to scare us.

One day they started moving prisoners again. They picked you from your tent, put you naked, shaved your head and beard (I was too young to have a beard), then beat you. They dressed you with orange clothes, handcuffed you, and put gloves with no fingers on you, so you couldn't open the handcuffs. 'You guys are going to a place where there is no sun, no moon, no freedom, and you're going to live there for ever,' the guards told us, and laughed. They put you in completely black glasses and headphones, so that you couldn't see or hear. With those on, you don't feel the time. But I could hear when they were changing the guards, probably every hour. I must have spent five hours sitting on a bench, with another detainee in my back.

Then they put us in a plane – I don't know what kind because I couldn't see. As soon as you moved or talked, they beat you. They were shouting: IF YOU DON'T FOLLOW OUR ORDERS, WE'LL KILL YOU! I passed out. We had no water and no food. I woke up hearing voices shouting at me in different languages. They took me to my cell. I saw soldiers everywhere, and guns, like if it was war. There were big metal fences everywhere. We were in Guantánamo, in Camp X-Ray. It's a prison without walls, without roofs – only fences. Nothing to protect you from the sun or the rain.
