(CNN)A recent crackdown on women's rights activists in Saudi Arabia has cast doubt over a much-touted reform agenda led by Crown Prince Mohammed bin Salman.
At least 11 women's rights activists have been arrested in recent weeks, according to rights groups, and are believed to be faced with counterterror charges punishable by up to 20 years in prison.
The State Security Presidency, a powerful security apparatus that reports directly to the King and 32-year-old Crown Prince, had been monitoring the detainees prior to their arrest, according to Saudi Arabia's official news agency.
At least four of the detainees have been released in recent days, according to Amnesty International.
But while the arrests were lauded in Saudi Arabia's mainstream press -- government-aligned media branded the activists "traitors" -- international groups and pundits, some close to the Saudi government, said the move was difficult to defend.
One Saudi activist who previously supported the Crown Prince's ambitious reform agenda said he has felt disillusioned by him in recent weeks, canceling plans to return to the kingdom.
Others staunchly opposed to the Crown Prince have said that the crackdown has "exposed the myth" of the reform agenda.
