One of the judges involved in the summary trial and execution of thousands of Iranian prisoners in the 1980s has been under treatment in a hospital in German city of Hanover. 

According to German media outlet Presseportal, Hossein-Ali Nayeri was admitted to a private neurosurgical clinic -- the International Neuroscience Institute (INI) -- headed by Madjid Samii, a prominent Iranian-born neurosurgeon.

Nayeri, a cleric, judge and chief adviser to Iran’s judiciary, was one of the main figures in the "death committee" responsible for the mass execution of political prisoners in Iran in 1988. President Ebrahim Raisi was also a key member of this committee. 

On July 7, Volker Beck, the president of the German-Israeli Society, notified Germany’s Federal Public Prosecutor, the Foreign Office, and the Federal Interior Ministry about Nayeri’s stay, urging them to initiate criminal prosecution measures against him.

While people are murdered and tortured to death in Iranian prisons, those responsible for the human rights violations travel to Germany with impunity, he said, stating, “This must come to an end.” He also referred to another Iranian judge -- Mahmoud Hashemi Shahroudi – who was treated in the same clinic in Hanover in 2018. 

In July 2022, Nayeri defended the massacre in an interview with the Islamic Republic Documents Center, a government entity that collects the history of the 1979 revolution and more than four decades of rule by the Islamic Republic in Iran.

He tried to justify and explain away the killing of thousands of political prisoners, saying, “The country was in a critical state. If Khomeini [the Islamic Republic's first leader] did not stand firm... perhaps the regime would have not been able to survive.”
