The half-brother and former heir of Jordan’s King Abdullah, Prince Hamzah, liaised with foreign parties over a plot to destabilise the country and has been under investigation for some time, the deputy prime minister says.
On Saturday the military said it had issued a warning to the prince over actions targeting “security and stability” in the key US ally.
Prince Hamzah later said he was under house arrest. Several high-profile figures were also detained.
“The investigations had monitored interferences and communications with foreign parties over the right timing to destabilise Jordan,” Deputy Prime Minister Ayman Safadi said in a televised news conference.
These included a foreign intelligence agency contacting Prince Hamzah’s wife to organise a plane for the couple to leave Jordan, he said.
“Initial investigations showed these activities and movements had reached a stage that directly affected the security and stability of the country, but his majesty decided it was best to talk directly to Prince Hamzah, to deal with it within the family,” he said.
Between 14 and 16 people had been arrested in connection with the plot, Mr Safadi said.
Efforts were underway to resolve the crisis within the royal family, but Prince Hamzah was not cooperative, he added.
“It’s a break from the traditions and values of the Hashemite family,” Mr Safadi said.
The developments are likely to rock Jordan’s image as an island of stability in the turbulent Middle East. King Abdullah removed Prince Hamzah from his position as heir to the throne in 2004, in a move that consolidated his power.
Although he has been marginalised for years, Prince Hamzah has angered the authorities by forging ties with disgruntled figures within powerful tribes.
These people, members of loosely organised groups known as Herak which in addition to their domestic presence represent a vocal opposition based abroad, have recently called for protests against corruption in a country hard hit by COVID-19’s impact on the economy.
Anger with the authorities over worsening living standards has in the past triggered major civil unrest.
Prince Hamzah said in a video passed to the BBC by his lawyer that Jordan’s rulers are corrupt and put their interests above those of the public.
“What Prince Hamzah said is repeatedly heard in the homes of every Jordanian,” said Ahmad Hasan al Zoubi, a prominent columnist, on his Facebook account.
The state news agency said on Saturday that Bassem Awadallah, a US-educated long-time confidant of the king, and royal family member Sharif Hassan Ben Zaid had been detained, among others.
Jordan’s neighbours and allies expressed solidarity with King Abdullah over the security measures in the kingdom, an important ally of the United States.
Saudi Arabia’s King Salman bin Abdulaziz and Crown Prince Mohammed bin Salman called King Abdullah on Sunday to affirm their support for the steps he is taking to preserve Jordan’s stability and security, state news agency SPA reported.
Earlier, Prince Hamzah’s mother Queen Noor, the widow of Jordan’s late king, defended her son.
“Praying that truth and justice will prevail for all the innocent victims of this wicked slander,” she wrote on Twitter. “God bless and keep them safe.”
Some opposition figures have rallied around Prince Hamzah in a move that has displeased the king, officials familiar with the situation said.
But most politicians believe Prince Hamzah will be silenced, with little prospect of him posing any threat given that the army and security forces who are the backbone of support for the Hashemite dynasty are firmly behind the monarch.
