Advertisement As the names of some those captured seeped out — many are still unknown — Jordanians were shocked. Most of those arrested hailed from the country’s so-called East Bank tribes, the powerful clans that for decades had been the monarchy’s sword and shield, its soldiers and statesmen. East Bankers consider themselves the country’s Indigenous inhabitants, rather than the Jordanians of Palestinian origin who came from areas west of the Jordan River. The arrests, officials say, were the result of a year-long surveillance operation by the army, police and intelligence service. In their telling, they struck just before the zero hour, averting a wave of chaos and discontent that Prince Hamzah hoped to unleash and ride into the palace to replace his half brother, King Abdullah II.
