Turkish Foreign Ministry spokesman Hami Aksoy said the investigation was "continuing intensively", and that the Vienna Convention allowed for consulates to be searched by the authorities of the host country with the consent of the mission chief.
That Saudi Arabia would allow foreigners to enter a consulate and search it shows the growing worldwide pressure the kingdom faces over the disappearance of Khashoggi, a contributor to the Washington Post.
Turkish President Recep Tayyip Erdogan said on Sunday he was awaiting the results of an investigation into Khashoggi's disappearance and maintains positive expectations on his fate.
Trump, speaking at the White House, said he does not know anything about Khashoggi's disappearance and that he had not yet spoken with Saudi officials about the situation.
If that doesn't happen soon, it's clear that Britain and its allies are likely to conclude that Saudi Arabia has crossed an unacceptable line. CNN reports that 15 Saudi nationals visited the consulate the same day as Khashoggi and have since left the country. Why don't you prove it?
Explosion reported at Irving Oil refinery in Saint John
Residents described feeling an explosion shortly after 10 a.m. 'We're sitting here and watching it burn right now, ' he said. Residents near the crude oil processing plant have reported hearing loud explosion coming from the 780 acre site.
Donald Trump commented on the disappearance in his press conference yesterday, saying "I do nor like it" and expressing hope that the issue will "sort itself out". He visited the consulate in Istanbul on October 2 to obtain documentation to finalize his divorce; his Turkish fiancée waited for him outside the building, and reported him missing after he didn't return.
Khashoggi, a Washington Post contributor who had been published in the Arab and Western media, vanished last Tuesday after visiting the consulate to obtain official documents. "It is going to put further stress on the relationship, particularly in terms of congressional views on Saudi Arabia", said Mr Gerald Feierstein, a veteran United States diplomat in the Middle East who served as ambassador to Yemen. The Foreign Ministry said Saudi officials have indicated their willingness to cooperate in the investigation. That team was sent "specifically for the murder", a person with knowledge of the Turkish investigation tells the Post.
Human rights activists and friends of Saudi journalist Jamal Khashoggi protest outside the Saudi Consulate in Istanbul, Turkey, October 8, 2018. Saudi Arabia is also unhappy about Ankara's growing proximity to the kingdom's Shiite rival, Iran.
Erdogan said "mere words [of Saudi officials] are not enough evidence".
"See, when I hear about an arrest of my friend who did nothing that worth to be arrested make me feel that I should not go home".
She expresses confidence in the Turkish government officials investigating and adds, "At this time, I implore President Trump and first lady Melania Trump to help shed light on Jamal's disappearance". "Right now, nobody knows anything about it, but there's some pretty bad stories going around".
Mr Trump had stayed silent on human rights as the USA backed the Saudi-led air campaign against rebels in Yemen, which a United Nations report said has killed thousands of civilians, and when Crown Prince Mohammed, often referred to by his initials MBS, detained dozens of people previous year in a controversial crackdown.
