“It is essential that the Crown Prince, who ordered the brutal murder of a blameless and innocent person, should be punished without delay,” Khashoggi’s fiancée Hatice Cengiz said in a statement posted on her official Twitter account in English and Arabic.

“This will not only bring the justice we have been seeking for Jamal, but it could also prevent similar acts recurring in the future,” she said.

Khashoggi, a US resident and critic of Prince Mohammed who wrote for The Washington Post, was killed and dismembered at the kingdom’s Istanbul consulate after going inside to receive paperwork for his wedding to Cengiz.

Cengiz said that “following this report, there is no longer any political legitimacy for the Crown Prince”. But she said the US report did not go far enough.

“The truth – that was already known – has been revealed one more time, and it is now confirmed.”

“Yet this is not enough,” she warned, “since the truth can only be meaningful when it serves justice being achieved.”

Campaigners frustrated over Biden’s decision not to sanction Saudi prince

Cengiz said if the crown prince was not punished, “it will forever signal that the main culprit can get away with murder which will endanger us all and be a stain on our humanity.”

The Saudi government, which initially said it had no information on Khashoggi, says it accepts responsibility for the killing but casts it as a rogue operation that did not involve the prince.

In a statement late on Friday, the Saudi foreign ministry said it “completely rejects” the declassified US report.
