The Washington Post has published the last known image of contributor Jamal Khashoggi before he disappeared following a visit to the Saudi consulate in the Turkish capital of Istanbul. Turkish authorities have said they believe Kashoggi, who has been frequently critical of Saudi Arabia in his writing, was killed at the building. However, the consulate insists he went missing after leaving through a back entrance. He was at the consulate to collect papers needed to marry his fiancee, Hatice Cengiz. She hasn't been told what happened to him, saying to WaPo: “I no longer feel like I am really alive. I can’t sleep. I don’t eat.” The image shows the writer stepping into the consulate. Turkish officials claim a team of 15 Saudis, who had arrived on two planes, carried out his killing shortly afterwards.
