Saudi Arabia's King Salman issued a wide-ranging overhaul of top government posts on Thursday, including naming a new foreign minister, following global fallout from the killing of Saudi writer Jamal Khashoggi almost three months ago.
Among those moved in the series of royal decrees announced on Saudi state television was Adel al-Jubeir, who had become one of the best-known Saudi officials in the West in his posts as foreign minister and, previously, as ambassador to the United States.
Jubeir was demoted to minister of state for foreign affairs, it added.
Assaf, a former long-serving finance minister and a board member of national oil giant Saudi Aramco, was among several people detained as part of a "corruption crackdown" in November, 2017.
Other notable changes include the appointment of Prince Abdullah bin Bandar bin Abdulaziz as chief of the National Guard, replacing Prince Miteb bin Abdullah.
A royal decree was also issued to restructure the Political and Security Affairs Council, headed by Crown Prince Prince Mohammed bin Salman, which has seen Saudi Arabia embroiled in its worst scandal in decades.

The kingdom has said Khashoggi was killed inside its Istanbul consulate in a "rogue operation" led by Saudi agents, but the Central Intelligence Agency reportedly concluded that Prince Mohammed ordered his assassination.
General Kalid bin Qirar al-Harbi was named general security chief, while Musaed al-Aiban was appointed national security adviser.
The CIA reportedly concluded that Prince Mohammed ordered Khashoggi's assassination.
In other changes, Turki al-Shabanah, an executive at broadcaster Rotana, was appointed as the new information minister, replacing Awwad al-Awwad - who was named as an advisor to the royal court.
One significant change impacts a close aide of the crown prince, Turki al-Sheikh, who was named as head of the kingdom's General Entertainment Authority, a body created in recent years to help organize and promote concerts and other events that had always been banned in the conservative country.
The king's eldest son, Prince Sultan bin Salman, was removed as head of the tourism authority. Prince Abdullah had been deputy governor of Mecca. The kingdom denies the crown prince had any involvement.
