Amid the chaos surrounding Saudi Arabia's admission of journalist Jamal Khashoggi's death in the Saudi consulate in Istanbul, United States President Donald Trump has warned against halting the Riyadh arms deal.

"We have $450 billion, $110 billion of which is a military order, but this is equipment and various things ordered from Saudi Arabia. It's over a million jobs; that's not helpful for us to cancel an order like that. That hurts us far more than it hurts them," CNN quoted Trump, as saying.

He, however, pointed out that the imposition of sanctions was being mulled over for Riyadh. "But there are other things that could be done, including sanctions," he added.

When asked about the Saudi official who was fired in connection with Khashoggi's killing, Trump asserted that he is not satisfied as there are questions that still need to be answered.

After days of denial, Saudi Arabia's Attorney General on Saturday confirmed that preliminary investigations pointed towards the death of Jamal Khashoggi, who went missing on October 2 after entering the Saudi consulate in Istanbul, Turkey.

The prosecutor added that his death was caused by a physical altercation which ensued in the consulate.
