Auschwitz remembered: 80 years on survivors deliver warning from history

Ceremonies have taken place to mark 80 years since the liberation of the Nazi death camp at Auschwitz-Birkenau in Poland by the Soviet Red Army.

More than a million people, most of them Jews, were murdered at Auschwitz, the largest ever mass execution of human beings.

About 50 survivors returned to the site to lay wreaths and candles and give speeches at the commemoration service.

World leaders also attended the ceremony. The Polish President Andrzej Duda said his country would always preserve the terrible memory of Auschwitz "in order to never let it happen again".

Fiona Bruce presents BBC News at Ten coverage of the ceremony, hearing first-hand testimony and with reports by Katya Adler, Daniela Relph, and Steve Rosenberg.
