Title of holocaust film?

I need help with the title of a film about the holocaust I saw in school. I remeber there was a lot of and they portrayed the gings and m shootings. People stood on the edge of a bank and were shot. I remember the bodies always had a bit of a yellow/green hue to them :/ and it showed them digging up the bodies and sticking them in a wood pile. This is about all I remember, we didn't see it all and there seemed to be no main character or any kind of plot. Just fictional brutality. Can anyone help me with the title of this film?
