No there isn't. You keep discounting ALL the eyewitness survivors telling the same story: Russian soldiers killed their relatives, some right in front of their eyes. According to you they are ALL lying to the western media.
Witness testimony from a warzone can be suborned with terror or hostages, or falsified.
Whereas it would be easy for someone with the right software to check the assertions made in the Southfront article.
If those assertions are correct, then the whole house of card falls. The Daily Mail or Maxar Technogies or both would be implicated in a cover up of murders apparently carried out on the 1st April, when the Russians were long gone.
Did you ... read the article yet?
