Is Saudi crown prince Mohammed bin Salman hiding his mother from the king?
Embassy says King Salman believes his third wife is receiving medical treatment overseas, but NBC reports her powerful son may have her under house arrest in a Saudi palace

Saudi Arabian Crown Prince Mohammed bin Salman has garnered international intrigue in the months since manoeuvring to become next in line for the throne.
Part of that plan was seemingly to hide his mother away from his father, the king – fearing she would block his power grab last June.
The crown prince has kept his mother’s whereabouts a secret from King Salman for more than two years, NBC News reported Thursday.
The Saudi Embassy in Washington denied the report, which added the king was told his third wife, Princess Fahda bint Falah bin Sultan, was often away for medical treatment.

Mohammed bin Salman came to power last June at 31, after serving as deputy crown prince and Defence Minister.
