The Crown Prince of Saudi Arabia has scrambled the kingdom's army in response to rumors that members of the royal family are planning to unseat him in a coup.
Military personnel and assets have reportedly been moved from eastern and western Saudi Arabia to Riyadh, as Crown Prince Mohammad bin Salman has left the country to attend today's G-20 summit in Argentina.
Any military reshuffling would likely be a pre-emptive move to deter any potential plotters from making a move while the Crown Prince, known as MBS, is abroad.
The claims made coincided with an interview with a dissident Saudi Prince who claimed a royal coup is in the offing, and that the opposition is mobilizing against the Crown Prince.
Prince Khalid bin Farhan al-Saud, who lives in exile in Germany, said that an opposition group has formed in Saudi Arabia with one goal: to unseat Crown Prince Mohammad bin Salman.
He said that if the royal family and 'other countries' decide to move against King Salman and the Crown Prince 'a wave of violence is likely to occur as the Saudi kingdom is reigned using ignorant and barbaric methods'.
'I hope that there will be a soft coup that overthrows the deep state and takes controls of prominent security institutions, and then sacks the Crown Prince and the king.'
His words backs up reports that there is a growing conspiracy among members of the House of Saud to ensure the favoured son does not become King when the 82-year-old King Salman dies.
Unlike European monarchies, the House of Saud is made up of hundreds of princes, with the power of succession drawn across tribal lines, rather than automatically going to the eldest son.
Each branch of the dynasty is consulted before a new King succeeds, but as the Crown Prince is now the de-facto ruler, an attempt to remove him from the equation would likely have violent consequences.
A preferred candidate of the opposition is Prince Ahmed bin Abdulaziz, 76, younger full brother of King Salman and uncle to Mohammad bin Salman.
Prince Ahmed was one of only three people on the Allegiance Council, made up of the ruling family's senior members, who opposed MBS becoming crown prince in 2017, two Saudi sources said at the time.
Senior U.S. officials have indicated to Saudi courtiers in recent weeks that they would support Prince Ahmed, who was deputy interior minister for nearly 40 years, according to Saudi sources with direct knowledge of the consultations.
These Saudi sources said they were confident that Prince Ahmed would not change or reverse any of the social or economic reforms enacted by MbS, would honour existing military procurement contracts and restore the unity of the family.
As well as dealing with enemies at home, Crown Prince Mohammad likely faces the cold shoulder in Argentina as he struggles to shrug off the lingering stigma of a the murder of journalist Jamal Khashoggi.
