Iran's Judiciary chief says imposing restrictions on Islamic Republic officials shows Washington's desperation in the face of the Iranian nation's resistance.
Ayatollah Sadeq Amoli Larijani's remarks came in reaction to a recent decision by US President Barack Obama to impose restrictive measures against eight Iranian officials.
He said the "arbitrary decision adopted without going through legal proceedings" belies Washington's claim that it abides by the law and advocates human rights.
Ayatollah Larijani criticized the double standards adopted by the West and in particular the US, in dealing with human rights issue, IRNA reported.
He further referred to a recent scandal surrounding the United States over an experiment which used Guatemalan prisoners and mental patients as test subjects without their knowledge.
"Today, those people who claim to be the advocates of human rights [are the same people who] many years ago performed medical experiments on the innocent people of one country (Guatemala) infecting them with sexually transmitted diseases in order to test [the efficacy of] their drugs on them."
Turning to the developments in Iraq, Ayatollah Larijani said the Iranian "people and government want to see security and stability in Iraq" and expressed hope for the "formation of a cabinet in the country after much political and military turmoil."
Earlier in the day Majlis Speaker Ali Larijani, Ayatollah Larijani's elder brother, condemned the sanctions against Iranian officials as "a cheap and meaningless" move.
