Saudi Arabia on Sunday threatened to retaliate for any sanctions imposed against it after President Donald Trump said the oil-rich kingdom deserves "severe punishment" if it is responsible for the disappearance and suspected murder of Washington Post contributor Jamal Khashoggi.
Turkish officials say Khashoggi, 59, was killed when he entered the consulate and his body was removed from the country by a Saudi hit team that arrived in Turkey the same day.
The Kingdom of Saudi Arabia is understood to be preparing a report in which it is likely to admit dissident journalist Jamal Khashoggi died during an interrogation at its consulate in Istanbul, according to a media report.
The king thanked Erdogan for welcoming the Saudi proposal for the joint group and said no one could undermine their relationship.

The president has sent Secretary of State Mike Pompeo to Saudi Arabia to investigate the disappearance.
On October 2, Khashoggi went to the Saudi consulate with his fiancée to get documents proving his divorce. Trump's argument that any such curtailment would entail a US economic sacrifice and would only open a market for Russian Federation and China to exploit is phony because his claim of securing $110 billion in military sales to Saudi Arabia is also phony. The Turkish prosecutor was seen leaving later, a Reuters witness said Tuesday.

Surveillance footage from cameras surrounding the consulate showed Khashoggi entering the complex but did not show him leaving.
