Kabul's dark prison was just that: a place where inmates spent their days and weeks in total blackness.
Other than during interrogations, which took place away from the cells, the only time the prisoners could see was in the brief moments when the guards used torches when bringing trays of food.

'The toilet in the cell was a bucket. Without light, you either find the bucket or you go on your bed,' Mohamed says.
'There were loudspeakers in the cell, pumping out what felt like about 160 watts, a deafening volume, non-stop, 24 hours a day.
'They played the same CD for a month, The Eminem Show.
'It's got about 20 songs on it and when it was finished it went back to the beginning and started again.
'While that was happening, a lot of the time, for hour after hour, they had me shackled.
'Sometimes it was in a standing position, with my wrists chained to the top of the door frame.
'Sometimes they were chained in the middle, at waist level, and sometimes they were chained at the bottom, on the floor.
'The longest was when they chained me for eight days on end, in a position that meant I couldn't stand straight nor sit.
'I couldn't sleep. I had no idea whether it was day or night.
'You got a shower once a week, with your arms chained above you, stripped naked, in the dark, with someone else washing you.
'The water was salty and afterwards you felt dirtier than when you went in. It wasn't a shower for washing: it was for humiliation.'
In Kabul, Mohamed says the food was also contaminated, and he often suffered from sickness and diarrhoea.
'The weight just dropped off me,' he said.
'The floor was made of cement dust. Whatever movement you made, the air would be full of cement and I started getting breathing problems.
' My bed was a thin mattress on the floor, surrounded by that dust.'
