U.S. Treasury Secretary Steve Mnuchin has pulled out of an investment conference next week in Saudi Arabia, as Riyadh continues to face questions about its involvement in the disappearance and alleged killing of a U.S.-based Saudi journalist in Turkey.

Mnuchin made the announcement Thursday on Twitter, following numerous Western corporate chiefs who have dropped out of the three-day gathering that starts Tuesday in Riyadh.

As reports from Turkey have mounted alleging Saudi agents tortured, killed and dismembered Jamal Khashoggi two weeks ago inside Riyadh's consulate in Istanbul, the chief executives announced they will not be attending the Future Investment Initiative conference.

Saudi Arabia has denied killing Khashoggi, a critic of the country's de facto leader, Crown Prince Mohammed bin Salman.

Saudi Arabia says it says it will disclose the results of its investigation into his disappearance.

The investment conference is being organized by Saudi Arabia's mammoth sovereign wealth fund and was being billed as a showcase for economic reforms advanced by Salman as he attempts to diversify the kingdom's economy, for decades focused on its role as the world's leading oil exporter.
