Fears are growing over the fate of a prominent Saudi journalist who has been missing since October 2 after entering Saudi Arabia's Consulate in Istanbul.
Turkish sources were quoted as saying on October 6 they believed Jamal Khashoggi, a critic of Saudi Crown Prince Muhammad bin Salman, was killed at the diplomatic mission.
One of the unidentified officials said that he was killed by a Saudi team sent "specifically for the murder."
An official at the consulate described the allegations as "baseless," adding that a security delegation of Saudi investigators was in Istanbul to probe Khashoggi's disappearance.
Turkish prosecutors opened an investigation into the case, and Prince bin Salman said that Turkish authorities were welcome to search the consulate, saying, "We have nothing to hide."
The Turkish Foreign Ministry has summoned Saudi Arabia's ambassador to ask for an explanation about Khashoggi's disappearance, which comes amid already strained relations between Turkey and Saudi Arabia.
Ankara has taken the side of Qatar over its blockade by Saudi Arabia and other neighbors, and Turkey's rapprochement with Iran has riled the Riyadh government.
