Saudi Arabia's King Salman bin Abdulaziz will stay in hospital for some more time to rest on doctors' advice after undergoing a colonoscopy on Sunday afternoon.
Saudi Press Agency (SPA) gave the information on Sunday citing the royal court of the country, reports Reuters.
It said the results of the colonoscopy were fine, and did not say exactly how long the kind would be in hospital.
SPA had reported earlier that the king was admitted to King Faisal Specialist Hospital on Saturday evening in the Red Sea city of Jeddah to undergo medical tests, also citing a statement from the royal court.
The king, 86, underwent gallbladder surgery in 2020 and had the battery of his heart pacemaker replaced in March.
King Salman, the custodian of Islam's holiest sites, became ruler of the world's top oil exporter in 2015 after spending more than 2-1/2 years as the crown prince and deputy premier.
