Auschwitz survivors reunited 70 years on

It has been 70 years since the Auschwitz concentration camp in Poland was liberated by Soviet soldiers.

It was the largest camp established by the Germans during World War II and has become synonymous with the Nazi plan to wipe out Europe's Jewish population.

More than a million people - the vast majority of them Jews - were killed there.

Fergal Keane has been speaking to some survivors who have returned to Auschwitz to remember those lost and to be reunited with fellow captives.
