Saudi King Salman will undergo medical tests on Sunday evening for lung inflammation, the state news agency said, citing a statement from the royal court, APA reports citing Reuters.
The brief statement did not reveal more details.
The 88-year-old king of the world's biggest oil exporter, a major U.S. ally in the Middle East, also received medical care for lung inflammation in May.
Salman last chaired a cabinet meeting in August, less than two weeks after a royal decree issued by him allowed the cabinet to convene in the absence of the king, crown prince or both.
