A Turkish official says the Saudi ambassador to Turkey has been summoned to the ministry for discussions over a Saudi journalist who disappeared after a visit to the Saudi Consulate in Istanbul.
The Foreign Ministry official says the ambassador was "invited" to the ministry on Thursday but did not provide further detail. The official spoke on condition of anonymity in line with government rules.
Jamal Khashoggi, who has written Washington Post columns critical of the kingdom's assertive crown prince, went missing on Tuesday.
