http://news.bbc.co.uk/2/hi/americas/7292974.stm A Yemeni man has described being held for nearly three years in secret CIA prisons, or "black sites", around the world and accused the US of torture.
Khaled al-Maqtari told Amnesty International he was held in isolation for more than 28 months without charge or access to any legal representation.
He said he first became a US "ghost detainee" at Abu Ghraib prison in Iraq after being arrested there in 2004.
The US has not acknowledged detaining Mr Maqtari.
