WASHINGTON (AP) — A report by a medical task force says Defense Department and CIA health professionals violated professional ethics standards by helping to develop interrogation and torture techniques and participating in force-feeding of terror suspects over the last decade.

While reports of torture following the attacks of Sept. 11, 2001 are not new, the report by the Institute on Medicine as a Profession said the U.S. should do a full investigation into how much military and intelligence physicians and psychologists participated in the interrogations, saying the record “remains fragmentary.”
