The half brother of King Abdullah, Prince Sattam bin Abdel Aziz, has died at the age of 72, according to official reports from the Saudi Press Agency. Prince Sattam, who served as the governor of the Saudi capital Riyadh since 2011, was the 30th son of the late King Abdul Aziz, who founded the kingdom. The Saudi royal family has not revealed the cause of his death, as is the case with most top officials. However, a royal court statement has confirmed that the prince will be buried today. The late Prince Sattam, known for supporting development and humanitarian causes, graduated from San Diego University in 1965 with a Bachelors degree in Business Administration.
