Allegations of abuse and neglect at a US detention facility in Afghanistan have been uncovered by the BBC.Barack Obama
Former detainees have alleged they were beaten, deprived of sleep and threatened with dogs at the Bagram military base.
The BBC interviewed 27 former inmates of Bagram around the country over a period of two months.
The Pentagon has denied the charges and insisted that all inmates in the facility are treated humanely.
All the men were asked the same questions and they were all interviewed in isolation.
It is a controversy that threatens to damage the image of the new administration in both Afghanistan and Pakistan.
