In Auschwitz in southern Poland - where darkness has fallen but where on this special day a light has been shone on the unspeakable horrors that unfolded here. Some 70 years ago tonight this most notorious of Nazi death camps was liberated.
For more than a million, mainly Jews, it was too late. But some survived this killing factory, and some survive still. 300 returned here for a special service of commemoration. Some were coming back for the first time - but in the dusk here all managed a slow walk along the railway track that delivered them to their ghastly fate .

Here are just some of the faces and stories of Auschwitz survivors 70 years on from the concentration camp's liberation.
