Iran's new president should face an international inquiry over the massacre of thousands of political prisoners, campaigners said yesterday. Ebrahim Raisi, who won a landslide election victory at the weekend, was on a four-man 'death commission' that oversaw the execution of regime opponents in the late 1980s. More than 150 former United Nations officials, human rights authorities and legal experts have demanded that the UN open an inquiry into the killings they say 'may amount to crimes against humanity'. It is estimated 4,000 to 30,000 people were condemned to death in 1988 by then-supreme leader Ruhollah Khomeini in two separate waves.
