Concentration camp

Concentration camps, sometimes referred to as labour camps (TV: Turn Left) or death camps, (TV: The Middle Men) were facilities used by the Nazis to dispose of what they considered to be undesirables in World War II. The Seventh Doctor said this included Jews, homosexuals, Gypsies and trade unionists — "anyone a bit different, anyone they don't like the look of." (PROSE: Timewyrm: Exodus) According to Jason Kane, the prisoners were used as slave labour, expected to survive with only scraps of food and clothing. (AUDIO: Just War) Most died.

Consequently, he attracted the attention of the Nazi authorities but nevertheless maintained his liberty. (AUDIO: Klein's Story)
