US intelligence officials believe a phone message to "tell your boss" after journalist Jamal Khashoggi was murdered was a reference to Saudi Crown Prince Mohammed bin Salman.

The New York Times has received a transcript of one of the recordings released by Turkey.

The newspaper says the telephone call was made by Maher Abdulaziz Mutreb, a security officer who frequently travelled with the crown prince.

Turkish intelligence believes Mutreb was speaking to one of the prince's aides and also used words to the effect that "the deed was done".

But officials in Ankara say the audio does not conclusively implicate Mohammed bin Salman.

So who is "the boss"? And will this new evidence lead somewhere?
