Earlier on Sunday, Jordan's Deputy Prime Minister Ayman Safadi said that Prince Hamza had liaised with foreign parties over a plot to destabilize the country.
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 Hamza 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 destabilize Jordan," Safadi said.
These included a Mossad agent contacting Prince Hamza's wife to organize a plane for the couple to leave Jordan, he said.
Many Jordanians were still grappling for answers in the aftermath of reports that Jordanian security forces foiled an attempt by Hamzah and some of his associates to topple the regime of King Abdullah.
People around Hamzah communicated with entities calling themselves “external opposition,” Jordanian Foreign Minister Ayman Safadi said Sunday. He did not provide details about the “external opposition.”
Sixteen Jordanians have been detained in connection with the case, including Bassem Awadallah, a former head of the royal court, and Sharif bin Zaid, a member of the royal family, Safadi said. He accused the detainees of planning to “undermine the security” of Jordan.
Safadi accused Hamzah of sending out a video message on Saturday night as part of an attempt to “distort the facts and gain local and foreign sympathy.”
Abdullah received phone calls on Sunday from the kings of Morocco and Bahrain and the emirs of Qatar and Kuwait, who expressed their countries’ “full solidarity” with Jordan.
The leaders also voiced support for all measures and decisions taken by Abdullah to safeguard Jordan’s security and stability, the Jordanian news agency Petra reported.
Saudi Arabia, Egypt, the United Arab Emirates and the Gulf Cooperation Council also voiced full support for Abdullah in maintaining security and stability in Jordan.
