In a Sunday night phone call, Turkish President Recep Tayyip Erdoğan and Saudi King Salman bin Abdulaziz discussed the disappearance of journalist Jamal Khashoggi.
Erdoğan stressed forming a joint working group to probe the case, said a Turkish presidential source, who spoke on condition of anonymity due to restrictions on talking to media.
Khashoggi, a Saudi journalist and columnist for The Washington Post, has gone missing since he entered the Saudi Consulate in Istanbul on Oct. 2.
On that same day 15 other Saudis, including several officials, arrived in Istanbul on two planes and visited the building while Khashoggi was also 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 -- are pressing for the case to be cleared up as soon as possible.
