Turkish officials tell NBC News that authorities believe the critic of Saudi Arabia was killed at the Saudi Consulate in Istanbul.
Turkish authorities believe that journalist and Saudi Arabia critic Jamal Khashoggi, who disappeared in Turkey last week, was killed at the Saudi Consulate in Istanbul, a senior Turkish official and another regional diplomat told NBC News.
The Washington Post, which published Khashoggi's work, reported Saturday that Turkey believed he was killed by a Saudi kill team, citing two people with knowledge of the investigation.
Khashoggi, a Saudi journalist who writes an opinion column for The Washington Post, disappeared last week after entering the Saudi consulate in Turkey's largest city and hasn't been seen since. Saudi Arabia's government has said Khashoggi left the consulate building and that they're looking into what happened to him afterward, while Turkey had said previously it believed Khashoggi was still in the consulate.
"The initial assessment of the Turkish police is that Mr. Khashoggi has been killed at the consulate of Saudi Arabia in Istanbul," the Turkish official told NBC News on Saturday. "We believe that the murder was premeditated and the body was subsequently moved out of the consulate."
The Washington Post, in a statement from editorial page editor Fred Hiatt, said the newspaper has been "enormously proud to publish his writings" and called Khashoggi a "committed, courageous journalist."
"If the reports of Jamal's murder are true, it is a monstrous and unfathomable act," Hiatt said.
A spokeswoman for the Saudi Embassy in Washington did not respond late Saturday to requestd for comment on the Turkish allegation.
If the Turkish allegation proves true, it would demonstrate an alarming willingness by Saudi Arabia to use force overseas to quash criticism and stifle opposition the political rise of Prince Mohammed, who has embarked on an ambitious but controversial campaign to modernize the kingdom.
In the process, Saudi Arabia under Crown Prince Mohammed bin Salman has drawn scrutiny for arresting women's activists and jailing princes and elites in an aggressive anti-corruption campaign. But the government is not known in the past to have sought to kill dissenters far beyond its sovereign borders.
The Turkish official did not speculate about who in the consulate killed Khashoggi or why, nor would the official say what evidence Turkish police had. The other diplomat briefed on the situation said that intelligence collected since the disappearance suggested that his body may have been removed from the consulate in boxes.
Khashoggi's disappearance appears to have played out as he sought documents related to a divorce that he needed for his upcoming marriage to a Turkish woman, four individuals with knowledge of his situation told NBC News.
Khashoggi had sought previously to obtain the needed papers through the Saudi Embassy in Washington, but had been directed to the consulate in Istanbul, prompting concerns for his fiancé that he was being lured into a trap, a friend of Khashoggi's said. After going to the consulate in Istanbul, he was told to return on a different day, two other individuals said. It was on that return visit that Khashoggi disappeared, they said.
Turkey and Saudi Arabia, both major regional powers, have long had tense political relations. But the relationship has been further strained over the last year amid Qatar's diplomatic spat with Saudi Arabia and the United Arab Emirates. Turkey has aligned itself with Qatar in that crisis, and the tiny, gas-rich nation recently reciprocated with a $15 billion investment to help Turkey weather its economic troubles.
The Saudi government has said emphatically that Khashoggi is neither still in the embassy nor in Saudi Arabia. On Saturday, the consulate allowed Reuters journalists to tour the building to see that he was not being held there, The Washington Post reported.
Crown Prince Mohammed, the powerful son of King Salman in line to be the kingdom's next ruler, has acknowledged that Khashoggi entered the Istanbul consulate but said that he departed "after a few minutes or one hour." He said Saudi Arabia doesn't know what happened to him but is investigating along with Turkish authorities.
"We are ready to welcome the Turkish government to go and search our premises," Crown Prince Mohammed said last week in a Bloomberg News interview. "If they ask for that, of course, we will allow them. We have nothing to hide."
