Malaysian Prime Minister Anwar Ibrahim is undergoing medical examinations and procedures and is expected to remain under observation for two days, his office announced on Monday. His press secretary offered no details about the nature of the procedures, saying only that they were advised by a team of medical specialists. Anwar, who turned 79 on Monday and has served as prime minister since November 2022, has a history of back and shoulder problems, though there is no indication that the current procedure is linked to those earlier conditions.
