DOCUMENTARY
How the Holocaust Began
BBC Two, 9pm
Six million is the figure most of us recall when we think of Hitler’s horrifying murder machine, but in this documentary – released ahead of International Holocaust Memorial Day this Friday – historian James Bulgin examines how millions more were shot and buried by the Nazis across Eastern Europe before the death camps were built, and how technology is now helping to record these crimes for the first time. The last instalment of The US and the Holocaust is on BBC Four at 10pm. Humza: Forgiving the Unforgivable

In this moving film, Youtuber Humza Arshad explores the possibility of forgiving the gang who stabbed his cousin to death, and talks to other victims who have faced similar crises of conscience.
