Please note we fought for a few hours deciding whether or not to report this on our website, simply because the evidence cannot be corroborated and confirmed. However, because we do not believe in hiding or suppressing any information, no matter how far out there they are, we will post the alert in its entirety. Please know that TrackingTerrorism is in no way affiliated with ACSA and the views of this article do not necessarily express the views of our analysts.
Good job of combining intelligence sources.
