After a short while, a guard came and took me inside the hall. Once there, he pulled down my blindfold for a few moments and I saw numerous bodies strewn on the ground. There were about 12 chairs with 12 ropes hanging above them. The guards were busy quickly bringing in the prisoners and putting nooses around their necks and the guards pulled at the legs of dangling prisoners until they died.... I saw some prisoners who were chanting, and this made the guards very hysterical. [One of the senior prison officials] attacked and hit them and yelled, “Kill all of these quickly! Finish them off!” I do not know what happened next. I was not able to stand up any more and I passed out. The next thing I felt was that they were sprinkling water at my face and a guard dragged me out.
