Holocaust survivors to mark the 70th anniversary of liberation of Auschwitz

Next week, the 70th anniversary of the liberation of the largest and most notorious Nazi concentration camp - Auschwitz in occupied Poland.

It is also Holocaust Memorial day and in the run up to it, we have a series of special reports including one from the National holocaust museum in Newark.

In Auschwitz more than a million people died.

Frank Bright was one of the survivors but his parents and most of his classmates did not get out alive.

He's 86 now and more determined than ever to keep their memories alive. You may find parts of Natalie Gray's report upsetting:
