See? It's all speculation... the unnamed source is merely saying that these soldiers in similar uniforms might either be Ukrainians, or rebels.The source said CIA analysts were still not ruling out the possibility that the troops were actually eastern Ukrainian rebels in similar uniforms
Now, if not only for that, how can we give any credence to this second-hand ambiguous report from an unnamed source? If if this journalist is not making it up to sell news, his "unnamed source" never said unequivocally that the soldiers were Ukrainian, so, this is hardly something that adds any new element to this investigation.
Here is the core of the issue:
Question: "Who shot MH17? Ukrainians, or Separatists?"
This *unnamed* source's answer: "Huh... They look Ukrainians. Oh wait, they actually might also be Eastern Ukrainians... I don't know, these uniforms are all similar."
Great! This really closes the case, huh?
