"Sednaya" death center: bodies dissolved in acid and rooms filled with clothes and shoes of the executed were found in the most terrible prison in Damascus, Syria.
The inspection of the prison in which opponents of Bashar al-Assad's regime were held continues for the second day.
The four-story building has many secret chambers and four levels underground. The rebels are breaking down the walls to get to everyone.
Instruments for torture, ropes on which prisoners were hanged, a press for crushing bodies, and mutilated bodies, dozens of which showed signs of being dissolved by acid, were found in the prison.
"Search and rescue operations in the Sednaya death camp unfortunately ended with only bodies dissolved in acid being found," writes Turkish journalist Abdusamed Dagül.
Anadolu reporters, following the rescue teams of the Syrian "White Helmets", found rooms filled with discarded shoes and clothes.
Rebels discovered the files of 29 people executed in this prison.
Many prisoners spent years and even decades behind bars, in "Sednai", also found children who were born in prison, writes the Associated Press.
Many people come to the prison in the hope of learning something about the fate of their arrested relatives.
American journalist Austin Tice, who was sentenced to prison in Syria 12 years ago, may be among the prisoners.
