Holocaust survivor preserves Treblinka in art

Israel is marking Holocaust Remembrance Day, commemorating the murder of six million Jews by the Nazis during World War II. Samuel Willenberg, who is now 87 years old, is one of the last two known survivors of the Treblinka extermination camp.

Treblinka was one of the most notorious Nazi death camps.

Part of the Nazis' "final solution", the camp in occupied Poland was dedicated to extermination, designed for efficient mass murder.

Between 1942 and 1943 around 870,000 Jews were killed there, according to Israel's Holocaust Memorial, Yad Vashem.

Not many of those who were sent to Treblinka lived to tell the tale.

Yad Vashem estimates that a few hundred people escaped from the camp, but only a few dozen of those survived the war.....
