70 years on, Argentine court declares ‘Operation Massacre’ a crime against humanity

July 19, 2026

In June 1956, Argentine security forces raided a house in Florida, Buenos Aires, where men had gathered—some listening to boxing, others awaiting news of an anti-government uprising—and arrested twelve men despite most having no connection to the rebellion plot. Five were executed without trial at a landfill in José León Suárez, while seven survived and went into hiding. Journalist Rodolfo Walsh investigated and exposed these illegal killings in his groundbreaking 1957 book "Operation Massacre," though perpetrators faced no accountability and Walsh himself was later killed by another dictatorship in 1977.

Who is affected

The five executed men: Nicolás Carranza, Francisco Garibotti, Carlos Alberto Lizaso, Mario Brión, and Vicente Rodríguez
Seven survivors who escaped, including Juan Carlos Livraga (now 94)
Victims' families, including Berta Carranza (daughter of Nicolás Carranza) and Alicia Rodríguez (daughter of Vicente Rodríguez, now 80)
Journalist Rodolfo Walsh (later assassinated in 1977)
The twelve men arrested at the Florida house on June 9, 1956
General Juan José Valle and Naval Frigate Lieutenant Raúl Tanco (rebellion leaders)
The perpetrators identified: General Pedro Eugenio Aramburu, Admiral Isaac Francisco Rojas, Juan Constantino Quaranta, Desiderio Fernández Suárez, and Rodolfo Rodríguez Moreno

What action is being taken

No explicit actions are currently described as ongoing in the article. The court ruling was delivered on June 22 of this year, and the reparation measures have been ordered by the court, but the article does not explicitly state these measures are currently being implemented.

Why it matters

This ruling represents the first time Argentina has officially recognized these 1956 executions as state-sponsored crimes against humanity committed without trial, charges, or legal basis. The significance extends beyond justice for these specific victims—it establishes legal precedent by making such crimes imprescriptible (without time limitations), addresses a decades-long coverup, and honors foundational investigative journalism that exposed state violence. Unlike victims' families from the 1970s dictatorship who had organized support networks, these families suffered in isolation for seventy years. The ruling validates their pursuit of truth and establishes an important historical record for education, helping ensure future generations understand these abuses and potentially preventing similar state violence.

What's next

The court has ordered the following next steps:
Restoring the executed men's names and honor
Publishing the judgment in national and provincial gazettes
Integrating proven historical facts into educational programs
Installing commemorative plaques where the raids and executions took place
Creating a memorial site at the José León Suárez landfill
