"In our article about General Fay's report into detainee abuse at Abu Ghraib (US army reveals wider Abu Ghraib abuses, page 17, August 26) we refer to CACI. CACI International provided interrogators at this detention centre and complained that we suggested, wrongly, that the report made findings that they were involved in the worst instances of prisoner abuse. We are happy to make clear that although there were some findings of prisoner abuse against CACI interrogators, they were not the most serious and they did not involve the instances of torture, rape or other sexual abuse identified in the report and which have been widely reported in the press and depicted in photographs."
