Iran Human Rights Monitor joins urgent international appeal to the UN to prevent a new massacre in Iran
23 July 2025 – An influential group of 314 international human rights experts, Nobel laureates, former UN officials, and political leaders has today issued an urgent appeal to the United Nations to take immediate steps to save the lives of political prisoners in Iran and prevent a recurrence of the 1988 mass executions.
Iran Human Rights Monitor (Iran HRM) is proud to be among the signatories of this joint appeal, initiated by Justice for the Victims of the 1988 Massacre in Iran (JVMI), in response to a sharp rise in death sentences and open calls in state media for mass killings.
An editorial published on 7 July 2025 in Fars News, affiliated with the Islamic Revolutionary Guard Corps (IRGC), praised the 1988 execution of over 30,000 political prisoners as a “successful historical experience” and called for similar measures against today’s political detainees.
The global signatories, representing voices from over 60 countries, warn that “the risk of another mass atrocity, reminiscent of the 1988 massacre, is alarmingly real.” They urge UN Special Rapporteur on Iran Dr. Mai Sato, High Commissioner Volker Türk, and UN member states to take a firm stance and condemn these incitements.
The full text of the statement follows below.
International Community Must Act to Prevent a Repeat of Iran’s 1988 Massacre
23 July 2025
We call on the global community to urgently confront the escalating wave of political executions and entrenched impunity in Iran. The risk of another mass atrocity, reminiscent of the 1988 massacre, is alarmingly real.
On 7 July 2025, Fars News—linked to the Revolutionary Guards (IRGC)—published an editorial praising the 1988 executions of over 30,000 political prisoners as a ‘successful historical experience’. The editorial, entitled ‘Why the 1988 Executions Should Be Repeated’, openly advocated for similar measures against current detainees, framing political dissent as a threat to national security. This rhetoric reflects a dangerous effort to normalise state-sponsored killings.
On 12 July 2025, three opposition activists—Farshad Etemadi-Far, Masoud Jamei, and Alireza Mardasi—were sentenced to death by Branch 1 of the Ahvaz Revolutionary Court after two years of torture, accused of ‘waging war on God’ (moharebeh) over their support for the opposition PMOI (MEK). In July 2025, the Supreme Court rejected a fourth request for judicial review for political prisoners Behrouz Ehsani and Mehdi Hassani, leaving them at imminent risk on death row. There are currently dozens of political prisoners on death row on similar charges.
Since President Masoud Pezeshkian took office, executions have surged—with over 1,300 carried out, some 650 in 2025 alone.
These incitements and executions echo the horrors of 1988, when a fatwa from then-Supreme Leader Khomeini led to mass executions targeting PMOI members and other dissidents. The July 2024 report from the UN Special Rapporteur on Iran described those extrajudicial executions and enforced disappearances as ongoing crimes against humanity and genocide.
Warning signs are mounting. On 4 July 2025, ten UN Special Procedures expressed alarm over the crackdown since hostilities began on 13 June 2025 and the subsequent ceasefire, noting that state-media rhetoric, including calls for ‘surveillance’ and ‘killings’, echoes the ‘1988 atrocities’. Political prisoner Saeed Masouri, a key figure in the ‘No To Executions Tuesdays’ campaign, recently smuggled out a letter from Qezel Hesar Prison after an attempt to forcibly transfer him. He warns that his removal is a prelude to executing others on death row and that, just as in 1988, ‘a crime is in progress’.
We must not repeat the silence of 1988.
We urge the UN Special Rapporteur on Iran, Dr Mai Sato, her colleagues in the Special Procedures, and the Independent International Fact-Finding Mission on Iran (FFMI) to condemn these incitements and executions. We call on UN High Commissioner Volker Türk to speak out unequivocally against Iran’s systematic human rights violations.
We further call on Canada and other co-sponsors of the UN General Assembly’s Third Committee resolution on Iran to include an explicit reference to the 1988 massacre in this year’s resolution.
The international community failed to act in 1988. It must not fail again. The responsibility to prevent these crimes against humanity from being repeated rests with the United Nations and its member states.
