The oldest known survivor of the Auschwitz-Birkenau concentration camp has died aged 108 in Debno, north-west Poland, officials say, according to BBC News.

A teacher, Antoni Dobrowolski was imprisoned for giving secret lessons during Germany's occupation of Poland.

Mr Dobrowolski was arrested by the Gestapo and sent to the Nazi concentration camp in 1942.

He was later transferred to the Gross Rosen and Sachsenhausen camps in Germany, before being freed in 1945.

"Auschwitz was worse than Dante's hell," he said in a video made when he was 103.

Education for Poles was restricted to just four years during the Nazi occupation, in an effort to suppress Polish culture.

Mr Dobrowolski was part of an underground effort to continue education for children.

Approximately one million people were killed by the Nazis at Auschwitz-Birkenau.
