Crown prince of Saudi Arabia Mohammad Bin Salman Al Saud.
Saudi Arabia has confirmed the arrest of 11 princes who staged a sit-in, at Qasr al-Hokm in Riyadh, against the government.
According to Saudi media, the princes protested outside a historical palace in Riyadh against the government's move to stop paying for the water and electricity supplied to the royal class.
Saudi Arabia's attorney general confirmed the arrest on Sunday stating that the princes had challenged Saudi Arabia's austerity measures.
The arrested princes, who disrupted "public peace and order" shall face trial, the attorney general added.
Saudi Arabia's 'austerity measures' include a set of moves aimed at boosting revenue and keeping a check on national funding.
Saudi Arabia is one of the economies to grapple with the global slump in oil prices.
The Middle Eastern country's push to diversify its oil-dependent economy led to the arrest of more than 200 princes in November 2017.
The princes are detained at Al-Hayer prison, south of Riyadh.
They also demanded compensation for one of their cousins who was convicted of murder and executed in the year 2016.
