US intelligence officials have said that Saudi Crown Prince, Mohammed bin Salman, ordered the killing of journalist Jamal Khashoggi.
The claim, which was first reported by the Washington Post, has been denied by the Saudi government, with the country's top diplomat saying the Crown Prince had "absolutely" nothing to do with the killing.
Mr Khashoggi, a Saudi who lived in the United States, was a columnist for the Washington Post and often criticised the royal family.
He was killed October 2 at the Saudi Consulate in Istanbul.

This week, US intelligence officials briefed members of the Senate and House intelligence committees and the Treasury Department announced economic sanctions on 17 Saudi officials suspected of being responsible for or complicit in the killing.
Saudi Arabia's top prosecutor said he recommended the death penalty for five men suspected of the killing.
The highest-level official incriminated in connection with the killing is former deputy intelligence chief, Ahmed al-Assiri, who was fired after mounting pressure from Turkey, and the rest of the world.
