This year marked the 70th anniversary of the liberation of Auschwitz Birkenau, the infamous Nazi death camp in southern Poland. At three o'clock that afternoon Soviet troops marched into the concentration camp, and found sets of twins who had been experimented on by a Dr Mengele. Today, many of those who survived are still tormented by flashbacks, and still living with medical conditions caused by the barbaric experiments. In a special edition of Newsnight four twin survivors share their stories.
