The State Department said that Ms. Bossa and Ms. Ibáñez Carranza had ruled to authorize the court’s investigation against U.S. personnel in Afghanistan. While they participated in an appeals decision that opened the way for that investigation, the court’s pursuit of the American role in Afghanistan was eventually dropped. Mr. Khan announced soon after taking office in 2021 that he would not pursue accusations of torture carried out by U.S. military and C.I.A. personnel in Afghanistan and at so-called black sites in other countries. No formal investigations of specific U.S. personnel have taken place, nor have warrants been issued.
