Salman himself has been accused of the crime — of either having ordered the killing or at least having been aware of it.
Saudi Arabian Crown Prince Mohammad bin Salman said Wednesday that the murder of Saudi journalist Jamal Khashoggi was a "heinous crime".
He added that Saudi Arabia was cooperating with Turkist authorities, and that "justice will prevail".
Salman made his comments at the Future Investment Initiative Forum in Riyadh. The gathering, nicknamed Davos in the Desert, has seen a number of cancellations since the news of Khashoggi's killing broke.
Khashoggi, a columnist for the Washington Post and a critic of the Saudi regime, was killed on October 2 inside the Saudi consulate in Istanbul, Turkey. A finger of accusation has since been pointed at Salman — for either having ordered the killing or at least having been aware of it.
