Saudi Crown Prince Mohammed bin Salman was involved in the assassination of Saudi journalist Jamal Khashoggi six months ago in Istanbul, an Amnesty International official said.
Khashoggi's killers who liquidated him inside the Saudi consulate in Istanbul on October 2 carried out their crime under the guidance of the Saudi crown prince for the latter's work, the official said.
Although Riyadh has denied any role to Mohammed bin Salman in the crime, he faces charges from several parties - including prominent members of the US Congress - that he was directly responsible for the crime carried out by a Saudi assassination team of 15 individuals.
A few weeks after Khashoggi was killed in a horrifying manner, the US press reported tapes intercepted by US intelligence that the Saudi crown prince sought to silence the voice of the critic who criticized his policies, both in articles he wrote in the Washington Post or during discussions at international research centers.
Amnesty International on Thursday called on the United Nations and many governments to open an impartial, thorough and independent investigation into the killing of Khashoggi and two days ago a similar call was made to the Secretary-General.
The organization said it did not trust the Saudi legal system, which said late last year that it had charged 11 suspects in Khashoggi's murder, adding that it refused to turn a blind eye to the murder crime it described as ugly.
In a statement published on Tuesday, Amnesty said it was clear that the Saudi government and other governments were covering up the issue in order to maintain security cooperation and arms deals.
In the same statement, she called for an independent international investigation as the only way to avoid blurring the effects of the crime. Six months after the assassination of Khashoggi, no real signs of justice had emerged in his case.
