The Summer of 1988

The Successor

On August 15, 1988, Grand Ayatollah Hossein-Ali Montazeri — Khomeini’s designated successor, the man chosen to lead the Islamic Republic after its founder’s death — walked into a room in Tehran and confronted the men who were carrying out the Supreme Leader’s latest order.

The order was the execution of political prisoners. Not a handful. Not after trials. Thousands — held in prisons across the country, many nearing the end of sentences issued by the regime’s own courts — were being systematically killed. Three-man panels asked prisoners a single question about their beliefs. The wrong answer meant death, usually within the hour. No lawyers. No appeals. Bodies loaded into refrigerated meat trucks at night.

Montazeri looked at the members of the Tehran Death Commission and said¹:

“The greatest crime committed during the reign of the Islamic Republic, for which history will condemn us, has been committed by you. Your names will in the future be etched in the annals of history as criminals.”

One of the men in that room was a twenty-seven-year-old deputy prosecutor named Ebrahim Raisi.

In 2021, Raisi became president of Iran.

The Cup of Poison

To understand why the Islamic Republic turned its prisons into execution chambers in the summer of 1988, you need to understand what happened in the weeks before.

By mid-1988, eight years of war with Iraq had exhausted Iran. The Abadan refinery — once the world’s largest — lay in ruins. And the world had helped Iraq do it.

Western firms built Saddam Hussein’s chemical weapons factories — Karl Kolb GmbH constructed the Samarra complex; Alcolac International shipped 500 tons of mustard gas precursor from Maryland.² Donald Rumsfeld arrived in Baghdad in December 1983 with full US intelligence on Iraq’s daily chemical weapons use — and didn’t raise the issue. CIA satellite imagery of Iranian troop concentrations was reportedly shared to calibrate chemical attacks. The UN Security Council issued only vague statements condemning “chemical use in the conflict” without naming Iraq — the US and UK actively lobbied to water down resolutions.

The War’s Toll:

200,000 to 220,000 Iranian military dead

Over $600 billion in damage

Oil production collapsed from 6 million to barely 2 million barrels/day

100,000+ chemical weapons survivors with chronic lung disease, progressive blindness, and birth defects

100,000 chemical shells fired in the Second Battle of Faw — in forty-eight hours

3,200 to 5,000 civilians killed at Halabja — the largest chemical attack on a civilian area in history

On July 3, 1988, the USS Vincennes, operating in Iranian territorial waters, fired two missiles at Iran Air Flight 655 — a civilian Airbus A300 climbing to cruising altitude. All 290 passengers and crew were killed.

For Khomeini and his inner circle, the message was clear: the world would tolerate unlimited violence to prevent an Iranian victory.

On July 18, 1988, Khomeini accepted UN Security Council Resolution 598, ending the war. He called it drinking the cup of poison. His words: “Woe to me for still being alive to drink the cup of poison… I submit myself to God’s will.”

The war was over. What happened next was planned before the ceasefire.

The Pretext

Six days after Khomeini accepted the ceasefire, the MEK launched its last gamble.

On July 24, 1988, the National Liberation Army — the MEK’s Iraq-based military wing, armed with Saddam’s tanks and artillery — drove across the border in Operation Forough Javidan (“Eternal Light”). They penetrated deep into western Iran, reaching Islamabad-e Gharb, apparently believing the regime was on the verge of collapse.

It wasn’t. The Iranian counterattack — Operation Mersad — crushed the invasion at the Charzabar Pass. Between 1,400 and 2,500 MEK fighters were killed.

The invasion failed militarily. But it succeeded as a pretext.

Intelligence Minister Mohammad Reyshahri had reportedly warned Khomeini earlier that released MEK prisoners could serve as a “fifth column.” The regime had been accumulating the machinery for a purge: thousands of political prisoners — many nearing the end of their sentences — sat in cells across the country. The MEK incursion gave Khomeini the justification he needed.

The speed of what followed tells you it was planned in advance. Within days, death commissions were formed. Prisoners held incommunicado for years were executed immediately. The infrastructure — commissions, questionnaires, execution chambers, refrigerated trucks — did not materialize overnight. It had been prepared. The MEK invasion was the trigger, not the cause.

The Question

Khomeini issued a fatwa — a religious decree that superseded every law the Islamic Republic had written. The text, kept secret at the time but later published in Montazeri’s memoirs, was explicit:

“Since the treacherous monafeqin do not believe in Islam and whatever they say stems from their deception and hypocrisy… those who are in prisons throughout the country and remain steadfast in their support for the monafeqin are waging war on God and are condemned to execution.”

The instruction to the executioners was equally clear: “The gentlemen who are responsible for making the decisions must not hesitate, nor show any doubt or concerns with detail… ignore the cumbersome bureaucratic procedures.”

Three-member panels — Death Commissions — were established in Tehran and at least thirty-two provincial cities.³ They were not courts. They were administrative processing units for killing.

The Tehran commission — the “Quadrumvirate” — consisted of Sharia judge Hossein-Ali Nayyeri, prosecutor Morteza Eshraqi, deputy prosecutor Ebrahim Raisi, and intelligence representative Mostafa Pourmohammadi. Similar panels operated in Mashhad, Ahvaz, Tabriz, Shiraz, Gilan, and Hamedan. In Tabriz alone, judge Mirza Najaf Aqazadeh reportedly signed more than 250 death warrants.⁴

The “trials” lasted two to five minutes. Prisoners were often blindfolded. No lawyers were permitted. No appeals existed. Many prisoners were told they were being interviewed for “amnesty” or “transfer” — and answered truthfully about their beliefs, unknowingly sealing their own death warrants.

The killing operated in two waves with two different theological charges. MEK members were charged with moharebeh — waging war on God. The test: “Are you willing to denounce the hypocrites?” “Will you walk through minefields for the Islamic Republic?” Leftists — members of the Tudeh Party, Fedaian-e Khalq, Komala — were charged with mortad — apostasy. The test: “Do you pray?” “Do you believe in God?”

The distinction mattered theologically but not practically. In both cases, the wrong answer meant death.

The Scale

The regime’s official position: fewer than 100 prisoners died.

The physical evidence disproves this.

The Data:

Source Count Method Reliability
Official regime <100 Denial Zero — disproven by physical evidence
Montazeri (Aug ‘88) 2,800–3,800 Internal judicial reports High — contemporaneous
Boroumand Center (Omid Memorial) ~3,200+ Verified names High — forensic floor
Amnesty International ~4,672 Verified names + grave analysis High — includes provincial data
MEK/NCRI 30,000 (claim) / 3,208 (list) Extrapolation / verified names Mixed — list verified, total unverifiable

MEK/NCRI	30,000 (claim) / 3,208 (list)	Extrapolation / verified names	Mixed — list verified, total unverifiable

The verified forensic floor is 4,000 executions.⁵ The probable total — given thirty-two known death commissions and high execution rates in provinces like Gilan and Khuzestan — is 5,000 to 7,000.

This was the largest mass execution of political prisoners in the Islamic Republic’s history. It happened in weeks.

Imagine receiving a prison sentence from a court — serving years — and then being told that sentence no longer applies, because a decree has retroactively condemned you to death for what you believe. That was the reality for thousands of prisoners in the summer of 1988.

The killing was not limited to adults. Armen Nersisian was executed at fifteen. Irina Kachaturian at seventeen.⁶ Some prisoners had been jailed at twelve or fourteen for participating in street protests, then executed years later — children who had been in state custody during the very events that supposedly justified the killing.

The Promotion

Here is what happened to the men who ran the death commissions.

Ebrahim Raisi — deputy prosecutor on the Tehran commission — rose through the judiciary to become its chief in 2019. In 2021, he became president of Iran. His presidency was a signal: the regime did not deny the massacre. It celebrated the man who carried it out. Raisi died in a helicopter crash in May 2024.

Mostafa Pourmohammadi — the intelligence representative on the Tehran commission — became Minister of Justice in 2013. When asked about 1988 in a 2016 interview, he said he was “proud to have carried out God’s order.”

Seyyed Alireza Avai — prosecutor on the Ahvaz commission — also became Minister of Justice.

Gholamhossein Mohseni-Ejei, the current head of Iran’s judiciary, has explicitly threatened “1988-style” retribution against protesters in 2022 and again in January 2026. The logic of 1988 is not historical. It is the operating doctrine of the Iranian judiciary.

Participation in the massacre was not an obstacle to advancement. It was a prerequisite. The regime’s DNA is inextricable from the blood of that summer.

The Erasure

The bodies were buried in secret. The primary mass grave in Tehran — Khavaran — was discovered by families who dug with their bare hands in late 1988, finding body parts and clothing in shallow soil. They named it La’nat-abad — the Place of the Damned.

For three decades, a collective of women — the Mothers of Khavaran — maintained a vigil at the site, defying beatings and arrests to preserve the memory of their dead. Maryam Akbari-Monfared, herself a prisoner, filed a formal complaint from inside prison demanding an investigation into her siblings’ execution. The regime’s response: denied her medical care and threatened new charges.

The destruction has accelerated. In 2022, authorities erected concrete walls around Khavaran. In March 2024, Baha’i graves at the site were destroyed. On August 11, 2025, heavy machinery leveled Section 41 of Behesht-e Zahra cemetery — a key site containing 1980s execution victims.⁷ Tehran’s Deputy Mayor Davoud Goodarzi admitted the site was bulldozed to build a “parking lot.”

The bulldozers are destroying the bones, clothing, and blindfolds that would allow DNA identification. Under international law, enforced disappearance is a continuous crime — it does not end until the fate of the disappeared is clarified. The Islamic Republic is not merely covering up a past crime. It is committing an ongoing one.

In 2022, a Swedish court convicted Hamid Nouri — who had operated at Gohardasht prison under the alias “Hamid Abbasi” — of war crimes and murder. The Stockholm District Court classified the conflict between the MEK and Iran as an International Armed Conflict, making the prison executions a war crime.⁸ Nouri was sentenced to life. In June 2024, he was released in a prisoner exchange. He walked free. But the verdict stands — a legal record that judicially validated the Corridor of Death, the fatwa, and the absence of due process.

The Honest Ledger

A note on numbers: when a verified atrocity enters political discourse, the mechanism of conflation often inflates the count by collapsing distinct events — battlefield casualties, prison executions, and cumulative killings across years — into a single figure. The inflation does not help the victims. It gives critics a target for dismissal and obscures the forensic record that would hold perpetrators accountable.

The widely cited figure of 30,000 dead is forensically unverified. It likely aggregates the 1988 prison massacres with battlefield casualties from Operation Mersad and cumulative executions from the entire 1981–1988 period. The verified forensic data supports 3,800 to 5,000, with a probable total of 5,000 to 7,000. Without exhumations and access to regime archives, the full count may never be known.

Nouri’s release in a prisoner exchange undermined the deterrent effect of universal jurisdiction — though the verdict remains a permanent legal record.

And the prisoners who were killed were not all innocents. Some MEK members had taken up arms against the state. Some leftist groups had engaged in violence. The regime’s own courts had already tried and sentenced many of them — to prison terms, not death.

That is precisely the point. These were people serving sentences issued by the Islamic Republic’s own judicial system. The fatwa retroactively converted prison sentences into death sentences — applied collectively, based on belief rather than action, without the right of appeal. It was extermination administered as bureaucracy, certified by theology.

The forensic floor of 4,000 executions in weeks — carried out by commissions that spent two minutes per prisoner, targeting people who had already been judged by the regime’s own courts, including children as young as fifteen — qualifies this as a crime against humanity by every legal standard that exists.

The men who did it became presidents and ministers. The graves are being bulldozed. The mothers are still waiting.
