Erdogan had promised the "naked truth" about the killing, saying: "Why has the body of someone who was officially said to be killed not been found yet?"

There was also no mention of an alleged audio recording that the Turkish authorities claim to have of Khashoggi's death that supposedly confirms he was tortured, killed, had his fingers cut off and was dismembered.
