Jordan's Prince Hamzah has said he will refuse to obey orders while being held under house arrest following accusations he plotted a coup against King Abdullah II - his half-brother - by the country's deputy prime minister.

'I am going to escalate and won't obey when they tell you you cannot go out or tweet or reach out to people and are only allowed to see the family,' he said in the recording he circulated to friends and contacts on Sunday.
