A 96-year-old man nicknamed the 'Accountant of Auschwitz' for his role in the infamous Nazi death camp is fit to serve time in prison, authorities in Germany have ruled.
Oskar Groening is one of the last remaining members of the Nazi machine still alive, and his case has rumbled on for several years.
Groening was convicted in July 2015 of being an accessory to the murder of 300,000 Jews and sentenced to four years in jail. He has yet to serve a single day, however, having remained free while prosecutors determined whether he was fit for incarceration.
However the Hanover public prosecutor has finally rejected his plea to avoid jail time.
The prosecutor said "We rejected the request of the defence for a reprieve. We believe he should serve his jail sentence."
However his lawyers are expected to mount a fresh legal challenge by claiming he isn't fit for prison life.
Groening's case has garnered international headlines, particularly given his matter-of-fact admission of the Nazis' culpability and his willingness to discuss the horrors witnessed at Auschwitz.
His testimony has been deemed of huge historical significance and a vital counterweight to the claims of Holocaust deniers.
