Oman's Sultan Qaboos bin Said is in "stable condition" and continuing a program of medical treatment, state television said on Tuesday, citing a statement from the sultan's office. Concerns had grown for the sultan's health after he made a short visit to Belgium for medical treatment this month and Omani authorities said nothing about his health after his return. Qaboos, 79, has ruled the Gulf Arab state since coming to power in 1970. *This story was edited by Ahram Online
