The oldest known survivor of the Nazi German death camp of Auschwitz-Birkenau, Antoni Dobrowolski, has died at the age of 108.

Official Auschwitz historian Adam Cyra, who works at the Auschwitz-Birkenau memorial and museum, said Mr Dobrowolski died in the town of Debno, in north-west Poland.

Mr Dobrowolski, a primary school teacher, ran secret classes during Germany's brutal World War II occupation of Poland, when the local population was barred from receiving an education.

Arrested in 1942 by the Nazis' Gestapo secret police, he was first sent to Auschwitz, in annexed Polish territory, and later transferred to Gross Rosen and Sachsenhausen, both in Germany.

He survived until the latter camp was liberated by Soviet and Polish forces in 1945.

Returning to Poland after the war, he first ran a primary school in Debno and then a secondary school.

Auschwitz-Birkenau is the most enduring symbol of the Holocaust, Nazi Germany's World War II campaign of genocide against Europe's Jewish population.

After the war's end in 1945, the prison camp was transformed into a memorial and museum by Poland.

A year after invading Poland in 1939, the Nazis opened what was to become a vast complex on the edge of the southern town of Oswiecim - Auschwitz in German - initially to hold and kill Polish prisoners such as Mr Dobrowolski.

They later expanded it to the nearby village of Brzezinka, or Birkenau, as they took the Holocaust to an industrial scale.

Of the 6 million Jews killed by the Nazis during the war, 1 million were murdered at the camp, mostly in its notorious gas chambers, along with tens of thousands of others including Poles, Roma and Soviet prisoners of war.
