Saudi Arabia's Crown Prince Mohammed bin Salman vowed to bring the killers of dissident writer Jamal Khashoggi to justice, describing the case as "so painful, horrible and unjustified."

Addressing a panel at the Future Investment Initiative conference in Riyadh, Prince Mohammed said that many parties attempted to exploit the incident to "drive a wedge between Saudi Arabia and Turkey."

"I want to convey them a message: they will not be able to do so as long as there is a Saudi king called Salman, and crown prince named Mohammed bin Salman in Saudi Arabia and a Turkish president named Erdogan," he said.

Khashoggi, a vocal critic of the kingdom's powerful crown prince, disappeared after a visit to the Saudi consulate in Istanbul on October 2. Riyadh later admitted he was killed inside.
