An international network of spammers are posting AI-generated images of Holocaust victims on Facebook, a BBC investigation into "AI slop" has found.

Organisations dedicated to preserving the memory of the Holocaust say the images are leaving survivors and families distressed.

They have also criticised Facebook's parent company Meta, saying it allows users on its platform to turn the atrocity into an "emotional game".

There are only a handful of genuine photos from inside the Auschwitz concentration camp during World War Two.

But in recent months, AI spammers have posted fake images purporting to be from inside the camp, such as a prisoner playing a violin or lovers meeting at the boundaries of fences - attracting tens of thousands of likes and shares.
