Police in Turkey believe that a missing Saudi journalist may have been killed inside Saudi Arabia's consulate in Istanbul and his body was driven out of the compound, Reuters reported on Sunday, quoting unidentified Turkish officials.
However, the Arab source that spoke to Al Akhbar said Khashoggi had been taken out of another entrance to the consulate in a white vehicle in coordination with a Turkish security official.
The official strongly denounced these baseless allegations and expressed his doubt that they came from Turkish officials that are informed of the investigation or are authorized to comment on the issue. Another said it was a "high possibility".
Mr. Khashoggi is one of Saudi Arabia's best-known journalists and political commentators.
Washington Post editorial page editor and colleague of Khashoggi, Fred Hiatt said that if it had indeed occurred, the murder was a "monstrous and unfathomable act".
On Tuesday, Khashoggi visited the Saudi consulate in Istanbul to collect a document certifying he had divorced his ex-wife.
Prince Mohammed said in an interview published by Bloomberg on Friday that the journalist had left the consulate and Turkish authorities could search the building, which is Saudi sovereign territory.
He said that Saudi officials say Khashoggi left the consulate, "but there is no record in the video footage".
Fearing he would be arrested or banned from traveling outside the kingdom, Mr. Khashoggi left his home country previous year and moved to Washington, D.C., where he lived in self-imposed exile.
Turkish prosecutors have begun an investigation into the case, officials said on Saturday, and a spokesman for Erdogan's AK Party said authorities would uncover his whereabouts.
The New York-based Committee to Protect Journalists demanded Riyadh give "a full and credible account" of what happened to Khashoggi inside the consulate.
She said Mr Khashoggi was required to surrender his mobile phone, which is standard practice in some diplomatic missions.
The journalist said he had been banned from writing in the pan-Arab daily Al-Hayat, owned by Saudi prince Khaled bin Sultan al-Saud, over his defence of the Muslim Brotherhood which Riyadh has blacklisted as a terrorist organisation.
Khashoggi's disappearance has drawn attention to Prince Salman's crackdowns on his critics.
Also included in these agreements are that part of these armaments will be manufactured in Saudi Arabia, so it will create jobs in America and Saudi Arabia, good trade, good benefits for both countries and also good economic growth. Human and women's rights activists, intellectuals and clerics have been arrested - meanwhile, Saudi Arabia is waging a war in Yemen that has triggered a humanitarian crisis. His criticisms of the royal family and its vast powers were delivered from his self-imposed exile in the United States and could not be dismissed as the complaints of a longtime dissident. "I can speak when so many cannot". Khashoggi wrote for The Washington Post, which ran a blank column earlier this week to help publicize his disappearance.
