Prominent former UN judges and investigators have called on UN human rights boss Michelle Bachelet to investigate the 1988 "massacre" of political prisoners in Iran, including the role of its current president, Ebrahim Raisi, at that time.
The open letter released on Thursday, seen by Reuters, was signed by some 460 people, including a former president of the International Criminal Court (ICC), Sang-Hyun Song, and Stephen Rapp, a former US ambassador for global criminal justice.
