This is getting interesting...
Among other things, this seems to suggest that Trukey might have eyes or ears inside a Saudi consulate. All the more interesting is that they are willing to oust that source to pin this on the Saudis. To burn a resource like that, Turkey must see a powerful leverage point.
Of course, all the above assumes the audio/video is what Turkey claims it to be. It's a little unclear if Turkey has passed any of this evidence on to other countries.
