Saudi Arabia's Crown Prince Mohammed bin Salman appointed as Prime Minister

The Custodian of Two Holy Mosques, King Salman bin Abdulaziz of Saudi Arabia, named his son and Crown Prince Mohammed bin Salman as the Kingdom's Prime Minister and his second son Prince Khalid as defence minister, a royal decree said on Tuesday.

The reshuffle kept another son, Prince Abdulaziz bin Salman, as energy minister, the royal decree, carried by state news agency SPA, said.

Foreign Minister Prince Faisal bin Farhan Al Saud, Finance Minister Mohammed Al Jadaan and Investment Minister Khalid Al Falih remained unchanged, the decree showed.

Prince Mohammed bin Salman had been the defence minister and Prince Khalid bin Salman, Crown Prince's younger brother, previously served as deputy defence minister.

King Salman will still preside the cabinet meetings that he attends, the decree said.

The 86-year-old king became Ruler in 2015.
