A senior Saudi prince was killed when the helicopter he was travelling in crashed near the border with Yemen, state television reports.
Prince Mansour bin Muqrin, the deputy governor of Asir province, was travelling with several officials when the helicopter crashed, Al-Ikhbariya news channel reports.
The cause of the crash is unknown.
It comes a day after a major purge of the kingdom’s political and business leadership, including several princes.
The detentions, ordered by an anti-corruption body led by the kingdom’s Crown Prince Mohammed bin Salman, targeted dozens of people, including 11 princes, four ministers and dozens of ex-ministers.
The unprecedented move is seen as an attempt to cement the power of the heir to the throne.
Prince Mansour bin Muqrin is the son of another former crown prince.
The wreckage of the plane was found on Monday, the interior ministry says, and a search is under way for any survivors.
The group was carrying out an aerial inspection of the region when it crashed, it adds.
