Considering the Iranians have been accused of everything under the sun since 1979 by the US, without a single shred of evidence, I think we can safely add this to the list of BS until proven otherwise
Western Propaganda media is becoming more desperate as their Ukro lemmings continue to get slaughtered. I suspect they plan to frame Iran by making such absurd accusations and then demand that Iran stop cooperation with Moscow. Typical arrogant western behavior.
