Prior to that, The Washington Post reported, citing a Jordanian palace advisor, that some 20 officials were arrested over allegedly plotting a coup d'etat, ousting King Abdullah II and replacing him with Prince Hamzah in a move that could seriously "threaten the country's stability".
Joint Chiefs of Staff head, Major General Yousef Huneiti said the prince had been "asked to stop some activities that could be used to shake the stability and security of Jordan".
The half-brother of Jordan's King Abdullah II says he has been placed under house arrest by Jordanian authorities and accused the country's leadership of corruption and incompetence.
Jordan's former Crown Prince Hamza Bin Hussein said in a video recording yesterday he was under house arrest and had been told to stay at home and not to contact anyone, Reuters reported.
He said his security detail was removed, and his phone and Internet service had been cut.
I am not responsible for the lack of faith that people have in their institutions.
It has reached the point where no one is able to speak or express an opinion on anything without being bullied, arrested, harassed and threatened. I am in my home alone with my wife, our young children, and I wanted to make this recording so that it is clear to the world that what you see and hear in terms of the official line is not a reflection of the realities on the ground. "Unfortunately, this country has become stymied in nepotism, in corruption, and in misrule and the result has been the destruction or the loss of hope that is apparent in pretty much every Jordanian", he said.
Jordan's King Abdullah II gives a speech during the inauguration of the 19th Parliament's non-ordinary session, in Amman, Jordan, December 10, 2020.
Abdullah stripped his half-brother Hamzah of his title as crown prince in 2004, saying he had made a decision to "free" him from the "constraints of the position" in order to allow him to take on other responsibilities.
US State Department spokesman Ned Price said Washington was "closely following" the events in its close regional ally. Nevertheless, King Hussein insisted on putting Hamzah next in line to the throne after Abdullah.
"We are... in touch with Jordanian officials. King Abdullah is a key partner of the United States, and he has our full support".
Also swept up in the dragnet - according to observers and activists on social media - was Prince Hamzah bin Hussein, one-time crown prince and stepbrother to Jordan's King Abdullah II.
Neighboring Saudi Arabia reacted swiftly to developments in Amman.
The arrests were announced by the state-run Petra News agency, quoting an unnamed official who said Sharif Hassan bin Zaid, a member of the royal family, and Bassem Awadallah, a prominent official who once ran the royal court, were arrested "for security reasons" along with "others" after "close monitoring".
Jordan's 59-year-old king came to power in 1999, when King Hussein before his death elevated the British-educated, eldest son from his first marriage from his relatively obscure position as head of Jordan's special forces to become the new monarch.
It declared independence in 1946, and despite having little oil wealth, severely lacking water and repeatedly being rocked by wars on its borders, Jordan has survived.
