Saudi Arabian King Salman has pledged continuity, hours after his accession to the throne following the death of his half-brother, King Abdullah.
The new king moved swiftly to appoint heirs and ministers, including one prince from the ruling dynasty's third generation.
King Abdullah died overnight, weeks after being admitted to hospital with a lung infection.
He was buried in an unmarked grave in Riyadh, following Friday prayers.
His burial was conducted in line with the traditions of Wahhabism - the ultra-conservative form of Sunni Islam followed by the kingdom - where funerals are austere and simple.
King Abdullah's body was wrapped in a shroud and taken by ambulance to the Imam Turki bin Abdullah mosque in Riyadh.
Following prayers, which were attended by Gulf heads of state as well as foreign leaders including Turkish President Recep Tayyip Erdogan and Pakistani Prime Minister Nawaz Sharif, his body was taken to a public cemetery and buried.

Within hours of acceding to the throne of the oil-rich kingdom, King Salman, 78, vowed to maintain the same policies as his predecessors.
"We will continue adhering to the correct policies which Saudi Arabia has followed since its establishment," he said in a speech broadcast on state television.
The new king's profile was updated on his official Twitter account, where he wrote: "I ask God to help me succeed in my service of the dear [Saudi] people."
He named another of King Abdullah's half-brothers, Muqrin, who is in his late 60s, as the new crown prince.
Interior Minister Prince Mohammed bin Nayef, 55, was appointed deputy crown prince, making him second in line to the throne and effectively smoothing the line of succession for years to come.
