The Red Cross has confirmed reports there is a second secret detention centre at the Bagram air base in Afghanistan.

The base is already home to the Parwan Detention Facility, which holds prisoners detained by US forces.

The ICRC says there is another structure on the Bagram air base where detainees are being held and, that since August 2009, the US authorities have been notifying it of names of people detained there.

In recent weeks, the BBC has logged the testimonies of nine former prisoners who say they were held at the facility.

They said they were deprived of sleep by US military personnel there.

In response to these allegations, Vice Admiral Robert Harward, in charge of US detentions in Afghanistan, denied the existence of such a facility, or abuses, and said the Parwan detention facility - the main jail in the area - was the only detention facility in Afghanistan.
