Markets rise in Abu Dhabi and Dubai; Trump issues threats of 'severe punishment'

Saudi Arabia's stock market tumbled in early Sunday trade on concerns about relations with the international community following the disappearance of the Saudi journalist Jamal Khashoggi.

Khashoggi, a prominent critic of Riyadh and a US resident, vanished on 2 October after visiting the Saudi consulate in Turkey. Ankara believes that he was murdered inside the building and his body removed.
