Saudi journalist and Washington Post columnist Jamal Khashoggi's fate is still uncertain since he went missing earlier this month.
Khashoggi has long been feared killed at the Saudi consulate in Istanbul after he entered on Oct. 2 and was never seen exiting.
On the same day, 15 Saudis, including several officials, arrived in Istanbul on two planes and visited the consulate building while Khashoggi was still inside, Turkish police sources said. All of the identified individuals have since left Turkey.
Saudi authorities have yet to give a clear explanation of Khashoggi’s fate, while several countries -- particularly Turkey, the U.S. and the U.K. -- have expressed their desire that the matter should be elucidated as soon as possible.
Khashoggi's fiancee Hatice Cengiz, who was waiting outside the Saudi Consulate in Istanbul, called Yasin Aktay, advisor to Turkish President Recep Tayyip Erdogan and Turan Kislakci, head of the Turkish-Arab Media Association as Khashoggi didn't return from the consulate.
The Istanbul Chief Public Prosecutor's Office launched an investigation on the same day into claims about Khashoggi's detention in the consulate building.
