has become the latest top business leader to draw  from the Saudi Arabian government as it faces difficult questions over its role in the disappearance of journalist Jamal Khashoggi.

Khosrowshahi said in a statement that he is withdrawing from a major business conference in the kingdom this month at which he was due to speak.

"I'm very troubled by the reports to date about Jamal Khashoggi," Khosrowshahi said in a statement late Thursday. "We are following the situation closely, and unless a substantially different set of facts emerges, I won't be attending the FII conference in Riyadh."
