Information referenced elsewhere in the article isn't very relevant unless there is a direct citation in the infobox on articles such as this one. The infobox did not have ref's. I would prefer sources beyond media to establish participants if possible given the importance of the information. I can always find "media" claiming CIA was involved in regards to practically anything involving Iran which is why I ask of this. Certainly some media is more credible than others but official sources claiming responsibility are even better.   chi?
