Eleven royal princes in Saudi Arabia have been arrested, according to Saudi authorities, allegedly after they protested over a decree that stops the government from covering the cost of their electric and water bills.

The princes also demanded "compensation for a death sentence implemented in 2016 against one of their cousins," Reuters reports.

This is the second time in two months that nearly a dozen princes have been arrested by authorities. In November, 11 princes were among the 200-odd people arrested in an anti-corruption sweep as Crown Prince Mohammed bin Salman consolidated power.

NPR's Jackie Northam reports that the new arrests were sparked by austerity measures put in place by the crown prince:

"Saudi Arabia's attorney general, Saud al-Mojeb, says the 11 princes were arrested after refusing to leave a palace in Riyadh over a decree that ordered the state to stop paying their utility bill. The princes were taken to a maximum security prison and face a number of charges. In a statement, Mojeb said no one is above the law. "The arrests are reflective of the hard-line stand by Crown Prince Mohammed bin Salman to push through austerity measures. ... But perhaps as a sign that the cuts are too deep, last week King Salman announced that state employees would receive a monthly bonus for the next year."

Saudi Arabia has been pursuing austerity measures — including imposing a new tax and cutting some subsidies and payments to royal family members — after years of low oil prices.
