The Post is reporting that Turkish officials have told their US counterparts that they have audio and video recordings that prove Jamal Khashoggi was killed in the Saudi consulate in Istanbul. It appears that the claimed video evidence is more circumstantial. The audio evidence would appear to be from listening devices either within or targeting the compound. According to the Post, the tapes the Turks claim to have essentially have the audio of Khoshoggi being interrogated, tortured and then finally killed.
As the Post describes it, the Turks are extremely leery of sharing the evidence. And it’s not clear they’ve shared it with the US, as opposed to describe it to their US counterparts. It’s a dicey situation. They clearly don’t want to out themselves or at least out the ways they bug diplomatic compounds.
