A Pakistani legal aid group says dozens of Pakistani prisoners held by the U.S. at an Afghan prison are at risk of falling into indefinite detention because negotiations have stalled between the U.S. and Pakistan over their return to Pakistan.

Justice Project Pakistan represents Pakistani prisoners held in Afghanistan and their families. The group says there are about 40 detainees believed to be of Pakistani descent at the Parwan Detention Facility, often referred to as Bagram prison.

Most were taken into custody by U.S. forces following the U.S. invasion of Afghanistan.

The report issued by the group Wednesday says negotiations between the U.S. and Pakistan stalled over concerns they might return to the battlefield or face inhumane treatment at home.
