Saudi Arabia on Sunday appointed former media chief Turki Aldakhil as its ambassador to the UAE just days after it was revealed that Saudi Crown Prince Mohammed bin Salman told him he would “use a bullet” on slain journalist Jamal Khashoggi.

It was billed as “the most detailed evidence to date” that the Saudi crown prince “considered killing” Khashoggi long before the veteran journalist was brutally slain in the Saudi consulate in Istanbul last year. Now the man who was privy to the incriminating conversation has been appointed the oil-rich Gulf kingdom’s top envoy to the United Arab Emirates (UAE).

In an explosive report published last week, the New York Times revealed that US intelligence intercepts had picked up a conversation between Crown Prince Mohammed and his aide, Aldakhil, during which Saudi Arabia’s de facto ruler said he would use “a bullet” on Khashoggi if he didn’t return to the kingdom.
