The Saudi royal family has denied involvement, instead scapegoating a number of Saudi agents who they say are responsible for the murder.
Saudi Arabia is the lynchpin of a USA -backed regional bloc against Iran but the crisis has strained Riyadh's relations with the West. Dozens of Western officials, bankers and executives shunned a big investment conference in Riyadh this week.
Salah Khashoggi, who holds dual U.S. -Saudi citizenship and had thus far been under a travel ban, departed Saudi Arabia on Wednesday.
