US President Donald Trump has threatened the kingdom with "severe punishment" if Khashoggi, who has been critical of Prince Mohammed, was killed inside its Istanbul mission. "I don't think any of our government officials should be going and pretending it's business as usual until we know exactly what's happened here".
Mr Trump indicated earlier this week he was reluctant to pull out of a multi-billion-dollar U.S. weapons deal with the Saudis to show White House anger if the missing journalist was killed by the Saudis.
The Washington Post reported on Friday that Turkish authorities shared audio and video recordings with United States intelligence suggesting that the journalist had been murdered in the Saudi consulate.
Saudi officials have flatly denied the allegation and claimed Khashoggi left the consulate but failed to provide definitive proof.
"We will take stern action with the Saudis if necessary, " he said.
Western tech-industry officials have backed away from NEOM in the wake of Khashoggi's alleged killing. "We believe it is not warranted given the long term relationship between the two countries, and Saudi being the swing oil producer".
Nevertheless, the Saudi Stock Exchange plummeted about 7 percent at one point Sunday on fears of economic fallout from the diplomatic dispute, before recovering some of its losses later in the day.
"One possible area of cooperation for the Turkish and Saudi authorities is how to make Khashoggi's disappearance disappear from the public limelight".
