Saydnaya Military Prison

Mazen al-Hamada was a 36-year-old man from Deir ez-Zor when he was arrested in 2011 for participating in anti-government protests. He was held at multiple detention facilities before being transferred to Saydnaya Military Prison.

At Saydnaya, al-Hamada was subjected to what Amnesty International documented as systematic torture: electric shocks applied to genitals and other sensitive areas; suspension by the arms for extended periods (a technique known as strappado); severe beatings with metal rods and cables; exposure to freezing temperatures while stripped of clothing.

He witnessed mass hangings. Saydnaya's executions — which Amnesty documented occurred on Tuesday and Wednesday nights, typically in the early hours between 2 and 4 AM — were conducted with precise procedures: prisoners were informed only at the moment of transfer, given a blindfold, and told nothing of what awaited them. Those who returned to the cells described hearing the sounds from below.

Al-Hamada described the starvation as deliberate: rations reduced to a level that produced visible wasting within weeks. He saw fellow prisoners die of hunger, of untreated infections, of injuries from torture that were never examined by the prison's nominal medical staff.

After his release and flight to Europe, al-Hamada became one of the most powerful living witnesses to Saydnaya. He testified before European parliaments, gave evidence in the Koblenz trial against former Branch 251 commander Anwar Raslan, and published detailed testimony that contributed to Amnesty International's 2017 report characterizing Saydnaya as a "human slaughterhouse."

In 2020, al-Hamada returned to Syria under circumstances that remain unclear — driven, by most accounts, by desperation and longing for his family. He was arrested at the Syrian border immediately upon arrival. As of December 2024 and the fall of Assad's government, his fate remained unknown.

**UPDATE — December 2024**: Mazen al-Hamada did not survive to see Syria liberated. News emerged in December 2024, days before Assad's government fell on December 8, that he had been executed while in detention. He was killed by the regime that he had spent years testifying against — just days before its collapse. He died in the same system he had escaped, testified about, and helped bring to international justice through the Koblenz trial. He was one of the last victims of Assad's detention apparatus before it ceased to exist.

The man identified as 'Khalid' in Amnesty International's 2017 report 'Human Slaughterhouse' was a civilian from Damascus province who was arrested in 2012 and held at Saydnaya for approximately two years before his release.

His testimony to Amnesty International's researchers describes the physical layout of the prison: the white building where civilians are held, accessible via a central corridor; the red building where military detainees are held under even harsher conditions; the basement where executions take place.

Khalid described the mechanics of the executions at Saydnaya with clinical precision:

Prisoners selected for execution were typically informed on the night of the execution, after evening prayers. They were blindfolded and taken from their cells to the basement. In the basement, they were made to stand on a chair, a noose was placed around their neck, and the chair was kicked away. There was no formal reading of charges or sentences. Many prisoners had never been tried.

He described how the bodies were disposed of: removed from the prison in refrigerated trucks, transported to a military hospital outside Damascus, and buried in mass graves in the desert east of the city. The family of the executed prisoner was given no notification. Their death might be recorded as "heart attack" or "respiratory failure" on whatever documentation existed.

Khalid survived. He described the weight of survival — the knowledge of what had happened to the men who had been taken from the cells next to his, the guilt of living when they had not.

Bara'a al-Sarraj was a 22-year-old university student from Damascus when he was arrested in April 2011 during the early weeks of the Syrian uprising. He had participated in a small protest near his university. He was taken by security forces, and his family received no information about his whereabouts.

His case was documented through the Caesar photographs. Among the 53,275 images Caesar smuggled out of Syria, forensic analysts identified a photograph matching a number that could be cross-referenced with administrative records his family later obtained. The photograph showed a young man, emaciated, with bruising on his face and torso, a number pinned to his arm.

His family spent three years trying to locate him — paying intermediaries, bribing officials, submitting formal inquiries that were ignored. In 2014, after Caesar's photographs were published, his mother identified his image in one of the leaked photographs. The number matched. The date of the photograph — approximately six months after his arrest — showed a body that had lost at least 30 kilograms.

His case became one of the documented examples in the formal presentation to the UN Security Council in January 2014. His mother, identified only by her first name in human rights reports, gave testimony describing:

'He was taken for going to a small gathering near the university. He didn't even carry a sign. The security men took him from the street. For three years we didn't know if he was alive or dead. Then we saw the photograph and we understood everything.'

Bara'a al-Sarraj is one of thousands of individuals whose fate is documented only through the Caesar photographs — the largest single archive of direct evidence of mass atrocity produced in the 21st century.
