Saudi Arabia’s 89-year-old King Abdullah is looking for an heir again Saturday after Prince Nayef bin Abdulaziz al-Saud passed away in Geneva. The country’s interior minister and the next in line to the throne, Nayef was thought to be 78. Nayef was only made crown prince in October of last year, however, after his brother, Sultan bin Abdul Aziz, passed away. The line of succession in Saudi Arabia is still from brother to brother, passing among the many sons of King Abdul Aziz ibn Saud, who established the modern Saudi kingdom. A statement from the king said that Nayef will be buried on Sunday following a prayer service in the holy city of Mecca.
