AMMAN, Jordan (AP) — Jordan’s Prince Hamzah has made his first public appearance since he was placed under house arrest last week. Hamzah prayed with Abdullah and other family members at the graves of their forefathers in what appeared to be an attempted show of unity on a major Jordanian holiday. Abdullah has tried to signal that the situation is under control. But Sunday’s staged event left it unclear whether the king and his half brother have ended the most serious public rift in the ruling family in decades. Hamzah was placed under house arrest following accusations that he was involved in a “malicious plot” to destabilize the kingdom. He denies the accusations.
