According to the website, the source is provided by the Sputnik website, it does not have a date or the name of the photographer. The Sputnik website says that this photo is provided by the newspaper RIA Novosti with the caption:
"Reproduction of the photo depicting Baby Yar ravine, the place where 100,000 Soviet people were executed. The original is at the State Archives of Film and Photo Documents of the Ukrainian SSR."
Of course, the death toll and profile description already make this photo dubious and show us that there is obvious pro-Russian or Soviet propaganda, but does anyone know where this photo originated?
