Washington (CNN) The State Department said Saturday that the US government has not drawn a final conclusion about who is responsible for Saudi journalist Jamal Khashoggi's brutal assassination.

The department's statement came amid reports that the CIA has assessed that Saudi Crown Prince Mohammed bin Salman personally ordered the killing of Khashoggi.

"There remain numerous unanswered questions with respect to the murder of Mr. Khashoggi," State Department spokeswoman Heather Nauert said in the statement Saturday afternoon. "The State Department will continue to seek all relevant facts."

President Donald Trump said later Saturday that it was "premature" to assess Prince bin Salman was responsible for Khashoggi's killing and added that there would be "a full report on Tuesday, and it will be very complete."

"We're going to come up with a report as to what we think the overall impact was and who caused it and who did it," Trump said while touring devastated homes in Malibu, California. "We're talking about a killing. We're not talking about anything else. We're talking about a killing, so who did it."
