The "Washington Post" newspaper quoted special sources close to the Saudi Crown Prince's assistants, Prince Mohammed bin Salman, as saying that he was preparing an official indictment for his cousin and predecessor in the post, Prince Muhammad bin Nayef, related to corruption and wasting the money allocated to the security services while he was the Minister of Interior.
The newspaper also published - among an article by author David Ignatius - information that Princess Sara Bint Sultan, the wife of Muhammad bin Nayef, was prevented from traveling before she was temporarily allowed to receive treatment, while her two daughters, Sarah and Lulwah, were prevented from accompanying her.
She added that the Saudi authorities prepared a list of charges similar to the former Saudi intelligence man, Saad al-Jabri, who is outside the country, but that the Interpol police considered them "political charges."
The writer said that Mohammed bin Salman uses his authority to punish entire families by preventing their family members from traveling simply because of his doubts that they may not return, or that they may join dissidents abroad.
The writer also quoted US officials as saying that the Saudi crown prince used the power to prevent him from traveling on a much larger scale than the advertiser, and that he planned - perhaps this year - to seize all powers of government from his father, King Salman bin Abdulaziz.
According to the same article, the majority of those banned from traveling are not aware of this in advance, and are surprised by their return from the airport or land ports.
The newspaper reported that the most prominent families totally banned from travel are the family of the late King Abdullah bin Abdul Aziz, and that 27 of his sons and daughters, including the princes Mutaib, Mashal, Faisal and Turki, and 57 of his grandchildren, are prohibited from traveling.
The author revealed that last August, the Saudi-American physician Walid Fatehi, who was arrested in 2017, was released, and that his release was made under American pressure, but he and his family are still not allowed to travel.
He also mentioned that many members of the Saudi preacher, Salman Al-Awda, who has been detained since 2017, are banned from traveling, and the same is true for Salah, the son of Saudi journalist Jamal Khashoggi, as the Saudi authorities were requesting the return of his father to the Kingdom in exchange for permission to travel.
