BAT YAM (Israel) - THEY are believed to be the last two survivors of the most chillingly efficient killing machine of the Nazi Holocaust: the Treblinka extermination camp in occupied Poland.

Samuel Willenberg and Kalman Taigman, 87-year-old Israelis, are devoting their final years to trying to preserve the memory of the 875,000 people systematically murdered in a one-year killing spree at the height of World War II. Almost all of them were Jews.

Only 67 people are known to have survived the camp, fleeing in a brazen revolt shortly before Treblinka was destroyed. Following the recent death of a prominent chronicler, Israel's national Holocaust memorial says the two Israeli men are now the final living link to one of the most notorious death camps in human history.

'The world cannot forget Treblinka,' said Mr Willenberg. 'Soon there will be no one left to tell,' added Mr Taigman.

Treblinka holds a notorious place in history as perhaps the most vivid example of the 'Final Solution', the Nazi plot to rid Europe of Jews.

Along with the lesser known Belzec and Sobibor camps, it was designed with the sole intention of exterminating Jews, and Treblinka was by far the deadliest. Victims, transported there in cattle cars, were gassed to death almost immediately upon arrival.
