Saudi Arabia's heir to the throne Crown Prince Sultan bin Abdel Aziz has died abroad after an illness, national TV reported. He was 85 years old.
The TV said Sultan died in the early hours of Saturday morning.
He was the half brother of the Saudi king, the kingdom's deputy prime minister and the minister of defence and aviation.
Sultan has had a string of health issues: he underwent surgery in New York in February 2009 for an undisclosed illness and spent nearly a year abroad recuperating in the United States and at a palace in Agadir, Morocco.
The report did not say where outside the kingdom he died or elaborate on Sultan's illness.
