In World War 2 Jews from Germany and Western Europe were transported eastwards, mainly to the slave labour and extermination camps in Poland (early 1942 onwards). In the early stages of the Holocaust (October 1941 on) some German Jews were taken to Riga in Latvia and slaughtered in mass open-air shootings. Others were sent to the ghetto in Minsk and Maly Trostenets death camp near Minsk. A few were dumped in the already overcrowded Warsaw Ghetto. Nearly all the extermination camps were in Poland.
