Tehran, October 22 (KCNA) -- Iran's judiciary ordered an investigation on Wednesday into human rights crimes committed by the United States -- a defiant response to a UN report on its own alleged rights violations and to the U.S. charge that Tehran planned to kill a Saudi envoy.

"We must open a special case for America's crimes in which there is an indictment for the crimes it has carried out in this country and other Islamic states," Ayatollah Sadeq Larijani was quoted as saying by the official news agency IRNA.
