CAIRO (Reuters) - Saudi Arabia\u2019s 84-year-old ruler, King Salman bin Abdulaziz, left King Faisal hospital in the capital Riyadh after recovery, state news agency SPA reported. The Saudi king, the custodian of Islam\u2019s holiest sites, was admitted to hospital on July \u202e\u202e20\u202c\u202c to undergo medical checks, after suffering from inflammation of the gall bladder, which he had removed later that week. In a video released by SPA, the king could be seen walking steadily out of hospital, followed by several aides and his son, Crown Prince Mohammed bin Salman, wearing a face mask. The king was walking with a cane, as he usually does. The king, who has ruled the world\u2019s largest oil exporter and close US ally since 2015, chaired a meeting via video from hospital last week before his surgery. In a video aired by state media outlets, he could be seen reading and leafing through documents.
