Fears are growing over the missing Saudi writer Jamal Khashoggi, after Turkish officials said they believed he had been murdered.
Mr Khashoggi, a Saudi national, was last seen visiting the Saudi consulate in Istanbul on Tuesday.
A Turkish official told the BBC that initial investigations indicated he was murdered there.
Saudi Arabia has denied the accusations, saying it is “working to search for him”.
Mr Khashoggi has contributed articles to the Washington Post’s opinion section. The Post said it would be a “monstrous and unfathomable act” if he had been killed.
An official of Turkey’s ruling AK Party told broadcaster CNN Turk there was concrete evidence in the case, although none has yet been presented.
When was he last seen?
Jamal Khashoggi went to the consulate on Tuesday to obtain a document certifying he had divorced his ex-wife, so that he could marry his Turkish fiancée, Hatice Cengiz.
