The Trump administration has said it has not reached a final conclusion on who was involved in the death of the Saudi journalist, Jamal Khashoggi.

Speaking in California, US President Donald Trump said that the killing “should never have happened”.

He said he would receive a report on Tuesday on who the US government believed killed Mr Khashoggi and what the overall impact of his murder is.

Mr Trump made the remarks hours after the State Department said the government was still working on determining responsibility for the death, despite a CIA assessment that Saudi Crown Prince Mohammed bin Salman ordered the killing.
