Germany prosecutes ex-Nazi camp guard aged 98 for his involvement in killing 3,300 People during WW2

German prosecutors have charged a 98-year-old man with complicity in the murder of some 3,300 people at a Nazi concentration camp in World War Two.

The man, not yet named, was an adolescent when he served as a guard at Sachsenhausen between July 1943 and February 1945, the indictment says.

He allegedly assisted in the "cruel and insidious" mass killing of inmates.

Since 2011, Germany has prosecuted ex-Nazis for complicity - not only for murder or torture as individuals.

But it is a race against time, as those indicted have been very old and some have died before going on trial.
