Ankara, Turkey (CNN) Saudi Arabia is preparing a report that will acknowledge that Saudi journalist Jamal Khashoggi's death was the result of an interrogation that went wrong, one that was intended to lead to his abduction from Turkey, according to two sources.

One source says the report will likely conclude that the operation was carried out without clearance and transparency and that those involved will be held responsible.

One of the sources acknowledged that the report is still being prepared and cautioned that things could change.

The Washington Post columnist was last seen in public when he entered the Saudi consulate in Istanbul in Turkey on October 2. Previously, Saudi authorities had maintained Khashoggi left the consulate the same afternoon of his visit, but provided no evidence to support the claim.

CCTV footage shows Khashoggi entering the Saudi consulate on October 2.

Khashoggi's fiancée, Hatice Cengiz, who was waiting outside the consulate, says she did not see him re-emerge.
