On the eve of the Holocaust Memorial, the head of the Simon Wiesenthal Nazi-hunter group says the search for Nazis will continue regardless of how much time has passed since the end of the war in 1945.

Efraim Zuroff known as the Chief Nazi Hunter is in charge of 'Operation last Chance 'and tasked with hunting down the few remaining Nazi's still alive.

EFRAIM ZUROFF, THE SIMON WIESENTHAL CENTER'S CHIEF NAZI HUNTER, SAYING:

"It's still critical to bring Nazis to justice. One is that the passage of time in no way diminishes the guilt of the killers. The fact that they were able to allude justice for many years doesn't change anything. Two, we don't think old age should protect people who committed mass murder

EFRAIM ZUROFF, THE SIMON WIESENTHAL CENTER'S CHIEF NAZI HUNTER, SAYING:

We are obviously at a very late stage, in another three, two to three years, this will no longer be possible so it should be done as quickly as it can be done".

Martha Weiss who is a Holocaust survivor from Hungary, asked why mercy should be shown, even after many years when Jews didn't have the same considerations

HOLOCAUST SURVIVOR MARTHA WEISS, SAYING:

"My feelings about any Nazi war criminal is that they were very lucky that they were able to live for 67 years in peace, they had much more chance than we Jews ever had and as I said I don't think they should be allowed to die because they are old. Did they care whether they are putting 90 year olds into the gas chambers, or whether they are putting a three-month old baby into the gas chamber?

On Thursday a two minute silence will be held at the Vad Yeshem Museum in Israel ,in remembrance of the six million Jews killed in the Nazi Holocaust.
