Nazi war criminal Klaas Faber, who escaped to Germany in 1952 after being sentenced to death in the Netherlands for his role in the murder of 22 people, has died at the age of 90 in Ingolstadt in Bavaria, AFP quoted a hospital source as saying on Saturday.Faber had been living in Inglostadt for decades, according to the source, and he had evaded numerous Dutch attempts to have him extradited to serve his sentence, which had been commuted to life in prison.Klaas Faber was a former member of the Nazi SS Silver Fir unit. He was sentenced to death in the Netherlands in 1947, escaping to Germany while awaiting execution. Faber was number two on the Simon Wiesenthal's most wanted Nazi war criminals list. A German court dismissed the charges against Faber in 1957, citing a lack of evidence. Bavarian authorities resisted all efforts by Dutch authorities to have Faber rearrested and extradited.Faber was a Dutch national, but was given German citizenship automatically as a member of the SS.He worked at the Westerbork transit camp in the Netherlands. His unit killed "anti-German" Dutch citizens during the German occupation of the Netherlands.
