Turkey says authorities have concrete information on missing Saudi journalist

Turkish authorities have concrete information on the disappearance of prominent Saudi journalist Jamal Khashoggi, who has been missing for six days, an adviser of Turkey's ruling AK Party said on Sunday.

Yasin Aktay told broadcaster CNN Turk that Khashoggi had not left the Saudi consulate in Istanbul, which he had entered on Tuesday to obtain documents for a forthcoming marriage, in "normal ways". The case would not go unsolved, Aktay said.

Late on Saturday, Turkish sources said that Turkish authorities believed Khashoggi had been killed inside the consulate last week, in what they described as the deliberate targeting of a prominent critic of the Gulf kingdom's rulers.
