A former concentration-camp guard is facing trial in Germany in what may be one of the country’s last trials of Nazi war criminals.

The 93-year-old, known as “Bruno D.,” is accused of aiding and abetting 5,230 murders as part of the force at the Stutthof concentration camp in Poland.

He will be tried in a youth court, as he was 17 and 18 at the time of the killings.

He attempted to cover his face behind a red folder as he was wheeled into the Hamburg court.

Between 63,000 and 65,000 people, including 28,000 Jews were killed at Stutthof, which was one of the last concentration camps liberated in 1945.
