A U.S. appeals court has reinstated a lawsuit by four former Iraqi prisoners who say they were tortured with sexual violence, electrical shocks and beatings at Abu Ghraib prison. The lawsuit accuses employees of the private military contractor CACI International of ordering military staff to torture prisoners in order to weaken them for questioning. A federal judge dismissed the lawsuit last year, saying he did not have jurisdiction, but Monday’s decision reinstates the lawsuit and sends it back to that judge.
