A State Department spokesman said a probe of “credible allegations of atrocities” will “help heal the wounds of conflict.” Special war-crimes envoy Pierre Prosper will take up the issue during a visit to Kabul in November. The Pentagon, which has denied all knowledge of the atrocities despite the presence of U.S. forces in the area, had no immediate comment. The plan is to start exhuming by early November; in the meantime the United Nations is sending officials to the site to ensure there is no tampering.
