Condemns the government of Iran for the 1988 massacre of political prisoners and for denying the evidence of crimes against humanity. Urges: (1) the Administration and U.S. allies to condemn the massacre and pressure the Iranian government to provide detailed information to the victims' families about their loved ones and their final resting places; and (2) the United Nations (U.N.) Special Rapporteur on the human rights situation in Iran and the U.N. Human Rights Council to create a Commission of Inquiry to investigate the massacre, gather evidence, identify the perpetrators, and bring them to justice.
