Obama pledges review of alleged mass grave in AfghanistanSeven years ago, investigators for the Boston-based group Physicians for Human Rights discovered what appeared to be a mass grave in northern Afghanistan.The bodies, they were told, were those of Taliban fighters who had been rounded up by Northern Alliance forces shortly after the U.S. invasion in 2001 and stuffed into metal shipping containers for transport to a nearby prison.By the time they arrived, allegedly hundreds — perhaps thousands — were dead from suffocation, while others were shot by guards, and their bodies dumped in a field.Susannah Sirkin, the deputy director of Physicians for Human Rights, joins Martin Savidge to discuss the Obama administration’s position on the case and the current state of the grave site in Afghanistan.
