Uch Sorn, survivor of Duch's jungle prison M-13A
In this 14-minute video, Uch Sorn (pictured in the image) - who survived Duch’s brutal jungle prison code-named M-13A - talks about his experience.
Uch Sorn, a farmer, was imprisoned at M-13A in the early 1970s, and was one of perhaps 10 people who survived the prison. Hundreds died, quite possibly thousands. M-13A was the precursor to S-21, and was the place where Duch learned his brutal skills.
The video is in Khmer and English, and was shot on an iPhone while the author was at the same time interviewing Uch Sorn for a BBC radio piece – so the camerawork is far from perfect.
