Auschwitz trial: Prosecutor on bringing Nazis to justice

After a four-month trial, a German court is expected to deliver its verdict on Friday on 94-year-old former Auschwitz death camp guard Reinhold Hanning.

The ex-SS guard is accused of being an accessory to the murder of at least 170,000 people at the camp.

Prosecutors are racing against time to bring others to trial. "Nazi hunter" Jens Rommel told the BBC's Jenny Hill about the challenges of his job.
