Watch Treblinka: Hitler's Killing Machine

The story of the Auschwitz concentration camp is well known. But could Treblinka have been just as horrific a death camp? Some claim 900,000 people were exterminated in this camp in Poland during the Second World War. It has been hard to confirm, as the Nazis destroyed most evidence surrounding Treblinka's existence. Now a team of forensic investigators will examine the site of this camp to try and uncover the truth about Treblinka.

Treblinka: Hitler's Killing Machine is a 2014 documentary with a runtime of 46 minutes.
