Documents just released from German archives have for the first time presented proof which show that Norwegian citizens worked in Nazi concentration camps during World War II.So far, three Norwegian citizens who worked in the camps have been identified, NRK reports. Two were in their twenties, one somewhat older.They were from the counties of Vestfold, Hedmark and Buskerud and worked in the Stutthof Camp in today’s Poland and at Mauthaausen in Austria.- We do not have an exact count of how many Norwegians altogether worked in the death camps, but I believe less than a hundred, says senior researcher at the Holocaust Centre in Oslo, Terje Emberland.
