>> Former guards called the prison the end of humanity. Inmates, a death sentence. Amnesty International is providing a glimpse insides Syria's Sednaya Prison, one of the most terrifying places to be locked up in the world. A new report from the human rights organization says up to 13,000 people were secretly hanged at the military complex, outside Damascus.
Amnesty spoke to former guards, detainees and officials. All described repeated torture, and the systematic deprivation of basic needs.>> No one knows the real numbers. No one knows the ugly kinds of torture that occurs inside.>> It alleges the hangings happened on a weekly basis, usually on Mondays and Wednesdays.
>> Groups of detainees of between 20 to 50 detainees would be taken from their cells, told that they would be transferred to civilian detentions. But instead of that, they were taken to a cell in another building, inside of Sednaya, where they would be hanged.>> Amnesty says the executions took place between 2011 and 2015, but are probably still being carried out.
It says they amount to war crimes, and are calling on the UN to investigate. The prisoners faced sham trials before military courts. Inmates included people critical of the regime and former military personnel suspected of disloyalty.>>
> The Syrian government has previously rejected similar reports, denying mass killing or mistreating detainees.
They take the head out of the cell or two others to be beaten. You hear sounds and your heart drops to the floor, you begin to shake, just can't control it.>>
