A handout picture provided by the Saudi Royal Palace on April 24, 2017 shows Saudi Arabia's King Salman bin Abdulaziz al-Saud attending a swearing in ceremony for new cabinet ministers and ambassadors in the capital Riyadh. Prince Khaled bin Salman, son of current King Salman, was named by Saudi Arabia on April 22, 2017 as ambassador to its major ally the United States in Washington, with which ties are improving under President Donald Trump. The change came among a series of orders issued by the king, who shuffled his cabinet, restored civil service benefits, and replaced the head of the army which for two years has been fighting rebels in neighbouring Yemen. / AFP PHOTO / Saudi Royal Palace / BANDAR AL-JALOUD / RESTRICTED TO EDITORIAL USE - MANDATORY CREDIT "AFP PHOTO / SAUDI ROYAL PALACE / BANDAR AL-JALOUD" - NO MARKETING - NO ADVERTISING CAMPAIGNS - DISTRIBUTED AS A SERVICE TO CLIENTS
