Saudi Arabia’s King Salman issued a wide-ranging overhaul of top government posts on Thursday, including naming a new foreign minister.

The announcement came following international fallout from the killing of Saudi writer Jamal Khashoggi nearly three months ago.

The king also ordered a shake-up of the kingdom’s two supreme councils that oversee matters related to the economy and security, respectively.

Both councils are headed by the king's son, Crown Prince Mohammed bin Salman, whose powers, including roles as deputy prime minister and defence minister, were untouched in the overhaul.

Adel al-Jubeir, the soft-spoken foreign minister who took over the post in 2015 from the late Prince Saud al-Faisal, was replaced by Ibrahim al-Assaf, formerly a longtime finance minister.

Al-Jubeir was appointed to the rank of minister of state for foreign affairs.

The changes appear to further consolidate the crown prince's grip on power by appointing advisers and members of the royal family seen as close to him.
