People hold posters of Saudi journalist Jamal Khashoggi during a protest organized by members of the Turkish-Arabic Media Association at the entrance to the Saudi Arabia Consulate in Istanbul on October 5, 2018.
'As journalists we are concerned by the fate of Jamal.
Jamal Khashoggi has not been seen since he went to the Saudi embassy on Tuesday to receive an official document for his upcoming marriage.
"We want to know his whereabouts".
Previously an adviser to senior Saudi officials, Mr Khashoggi moved overseas after his Saudi newspaper column was cancelled and he was allegedly warned to stop tweeting his criticisms of the crown prince's policies.
U.S. President Donald Trump has blamed the Organization of the Petroleum Exporting Countries (OPEC) for high crude prices and called on it to boost output to bring down fuel costs before the U.S. congressional elections November 6. She added that "the burden of proof is on Saudi Arabia" to prove that the journalist left the consulate in peace.
"We believe that Jamal Khashoggi is the consulate's "host" and call for his immediate release, or to tell us where he is", Kislakci added.
Turkey has said it believes Khashoggi is still inside the consulate.
When asked whether U.S. -Saudi relations were just as good as they were 24 hours ago before the President said these things, the Saudi leader replied in the affirmative, saying if you look at the picture overall, you have 99 percent of good things and one bad issue.
It said the consulate was working with Turkish authorities "to uncover the circumstances" of his disappearance.
Saudi Arabia's crown prince, Mohammed bin Salman, said in an interview published by Bloomberg on Friday that Turkish authorities were welcome to search the Saudi consulate in Istanbul for Jamal Khashoggi, a prominent Saudi journalist who visited the mission earlier this week and has not been heard from since.
Hatice said she waited for Mr Khashoggi outside the consulate from about 13:00 (10:00 GMT) until after midnight and did not see him leave. "We don't have information to the contrary", Ibrahim Kalin said.
Khashoggi, a former government adviser who went into self-imposed exile in the USA past year to avoid possible arrest, has been critical of some of the policies of Saudi Crown Prince Mohammed bin Salman and Riyadh's intervention in the war in Yemen.
Notably, Khashoggi would not be the only Gulf national to have been arrested overseas to be returned to the kingdom, and other incidents have been far more public.
Over the past years, Riyadh has also redefined its anti-terrorism laws to target activism. For instance, Nawaf Talal al-Rasheed, a Qatari national and a cousin of famed Saudi academic and critic Madawi al-Rasheed, was arrested in Kuwait and passed to Saudi authorities "under bilateral mutual security arrangements between Kuwait and Riyadh". Nimr had been arrested in Qatif in 2012.
