He said an investigation is being carried out and "once charges are proven against someone, regardless of their rank, it will be taken to court, no exception made."

Khashoggi's body has not been found.

Bin Salman said in the interview there "isn't an official statement announced by the American government" saying he ordered the killing.

After being questioned about the CIA's conclusion that he ordered the killing, the leader said he wants "this information to be brought forward."

"If there is any such information that charges me, I hope it is brought forward publicly," he said.

Speaking on how the journalist's death may have affected the US-Saudi relationship, Bin Salman said the "relationship is much larger than that."

"Our role is to work day and night to overcome this and to make sure our future is much better than anything that happened in the past," he said.

MBS says US and Iran should craft a new deal

Bin Salman said in the CBS interview the only reason for Iran to attack the facilities is "stupidity."

"There is no strategic goal. Only a fool would attack 5% of global supplies. The only strategic goal is to prove that they are stupid and that is what they did," he said.

A war between Saudi Arabia and Iran would mean a "total collapse of the global economy," the crown prince said.

"The region represents about 30% of the world's energy supplies, about 20% of global trade passages, about 4% of the world GDP. Imagine all of these three things stop."

He said he hopes Saudi Arabia and Iran can reach a "political and peaceful solution" rather than a military one.

Bin Salman said the leaders should craft a new deal.

Saudi Arabia wants to negotiate end to Yemen war, leader says

In the Sunday interview, the Saudi Arabian leader said his country was working to negotiate an end to the war in Yemen "every day."

"If Iran stops its support of the Houthi militia, the political solution will be much easier," Bin Salman said. "Today we open all initiatives for a political solution in Yemen. We hope this happens today rather than tomorrow."

What MBS said about jailed female activist

When asked if it's time to let her go, Bin Salman said the decision is not up to him, but up to an independent public prosecutor.

If the claims that she's been tortured in prison are correct, he said he will "personally follow up on this matter."

"If this is correct, it is very heinous," he said. "Islam forbids torture. The Saudi laws forbid torture. Human conscience forbids torture."
