Turkey says it will search the Saudi consulate in Istanbul as part of an investigation into the disappearance of a missing Saudi journalist, a week after he vanished during a visit there.
The announcement came as the Washington Post newspaper published a surveillance image of Jamal Khashoggi walking into the consulate just before he disappeared.
Turkish officials have said they fear the columnist was killed inside the premises.
Saudi Arabia has called the allegations that it killed 59-year-old Khashoggi "baseless" but has offered no evidence to show that he ever left the building.
Tuesday's statement from the Turkish Foreign Ministry says Saudi authorities will allow the consulate building to be searched, although it didn't say when that will happen.
The surveillance image released by the Post bore a Turkish caption bearing Khashoggi's name and saying he was arriving to the consulate.
The door Khashoggi walked in through appeared to be the main entrance of the consulate.
However, the consulate has other entrances and exits as well, through which Saudi officials insist he left.
Khashoggi had gone to the consulate in Istanbul for paperwork to marry his Turkish fiancee

He had been living since last year in the United States, in a self-imposed exile, in part due to the rise of Saudi Crown Prince Mohammed bin Salman, the son of King Salman.
Khashoggi has written extensively in the Washington Post about Saudi Arabia, including criticising its war in Yemen, its recent diplomatic spat with Canada and its arrest of women's rights activists after the lifting of a ban on women driving.
Turkish President Recep Tayyip Erdogan on Monday urged the Saudis to back up their claim that Khashoggi left the consulate.
"Now when this person enters, whose duty is it to prove that he left or not? It is (the duty) of the consulate officials," Erdogan said during a visit to Hungary.
"Don't you have cameras and other things? Why don't you prove it, you have to prove it."
