AMMAN, Jordan

Queen Noor, the mother of Jordan’s former crown prince Hamzah bin Al-Hussein, on Sunday voiced hope that “truth and justice will prevail” after accusations linking her son to actions harming Jordan’s security.

"Praying that truth and justice will prevail for all the innocent victims of this wicked slander," Queen Noor wrote on Twitter. "God bless and keep them safe."

On Saturday, former crown prince Hamzah and former head of the Jordanian Royal Court Bassem Ibrahim Awadallah were among some 20 people reportedly detained on the grounds that they "pose a threat to Jordan’s stability”.

In a statement by the Jordanian Chief of Staff, Gen. Yousef Huneiti, denied that Prince Hamzah was detained or under house arrest but confirmed he was asked to stop activities that are used to target Jordan's security and stability.

Prince Hamzah, however, appeared in a video saying that he was under house arrest and was accused of being part of meetings that criticized the King.

"I am not part of any conspiracy or nefarious organization or foreign-backed group, as is always the claim here for anyone who speaks out,” the prince said.

Prince Hamzah, 41, is the half-brother of King Abdullah II of Jordan, and the eldest son of late King Hussein bin Talal from his last wife.

He was declared a crown prince on Feb. 7, 1999, but he was replaced on Nov. 28, 2004 by King Abdullah II's eldest son, Hussein bin Abdullah, who was appointed to the post by his father.
