(CNN)Turkish authorities have audio and visual evidence that shows journalist Jamal Khashoggi was killed inside the Saudi consulate in Istanbul just over a week ago, a source familiar with the ongoing investigation told CNN.
The evidence, which was described to the source by a Western intelligence agency, showed there had been an assault and a struggle inside the consulate. There is also evidence of the moment that Khashoggi was killed, the source said.The foreign intelligence service found the nature of the evidence, which was provided in a briefing from Turkish officials, to be “shocking and disgusting,” the source told CNN. Khashoggi, a columnist for the Washington Post, walked into the consulate in Istanbul on October 2 intending to get paperwork that would allow him to marry his Turkish fiancée. He hasn’t been seen in public since.Saudi Arabia firmly denies any involvement in his disappearance and says he left the consulate that afternoon. His fiancée, Hatice Cengiz, who was waiting outside, says she did not see him re-emerge. Turkey has called on Saudi officials to provide evidence that he left the consulate, as they claim.CCTV images show Jamal Khashoggi entering the Saudi consulate in Istanbul on October 2.Read MoreThe Washington Post reported late Thursday that the Turkish government had told US officials that it was in possession of audio and video recordings proving that Khashoggi was killed in the consulate, citing unnamed US and Turkish sources.The audio recording in particular provided “persuasive and gruesome evidence” that a Saudi team dispatched to Istanbul was responsible for Khashoggi’s death, the Post reported.The fate of Jamal Khashoggi could cause trouble for Mohammed bin Salman“You can hear his voice and the voices of men speaking Arabic,” one person with knowledge of the recording told the Post. “You can hear how he was interrogated, tortured and then murdered.” International pressure has mounted on Saudi Arabia to explain what happened to Khashoggi, a former Saudi royal insider who became a critic of the regime and Crown Prince Mohammed bin Salman.The business world has also signaled its disquiet, with British tycoon Richard Branson saying he’s pulling back from two tourism projects in Saudi Arabia and has suspended discussions with Riyadh about a $1 billion investment in Virgin’s space companies. Business leaders have also started pulling out of a key conference hosted by MBS in late October.CNN confirmed Friday that it too would no longer participate in the Saudi Future Investment Initiative conference, known as “Davos in the desert.” CNN was a media partner for the event. US Treasury Secretary Steven Mnuchin told broadcaster CNBC he still planned to attend the Riyadh summit despite concerns about Khashoggi’s status.Focus on 15 men Turkish authorities believe 15 Saudi men who arrived in Istanbul on October 2 were connected to Khashoggi’s disappearance and possible killing. At least some of them appear to have high-level connections in the Saudi government.On Thursday, a US official familiar with the intelligence told CNN that the US had intercepts of Saudi officials discussing a plan to lure Khashoggi back to Saudi Arabia and detain him.Washington’s “working assumption” is that Khashoggi was killed inside the consulate in Istanbul, according to a US official familiar with the latest intelligence. “We are pretty clear eyed it is likely to have happened and it didn’t end well,” the official said. The source did caution that this was the latest assessment and no conclusions had been made.

The source says that Khashoggi rejected the ideas and over the following months his much sharper criticism of the government, in its domestic policy and relating to the crisis with Qatar, ended any dialogue. The source, who maintains high-level contact inside the kingdom, says that senior figures in the Royal Court in Riyadh were especially infuriated by Khashoggi’s criticism of the decision by the Saudi authorities to classify in September 2017 the Muslim Brotherhood and the Islamic scholar Yusuf al-Qaradawi as terrorists. At the same time, the source says, Khashoggi became more wary of returning to the kingdom.Saudis discussed plan to lure Jamal Khashoggi to Saudi Arabia, US intercepts showThree days before his disappearance, Khashoggi — speaking to a BBC journalist in an off-air conversation after a radio interview — said he did not think he would ever be able to return to Saudi Arabia.Asked when he might be able to go home again, Khashoggi says: “I don’t think I’ll be able to.”The BBC several days ago said it decided to publish the off-air conversation “in light of the current circumstances.””When I hear of an arrest of a friend who did nothing… makes me feel I shouldn’t go,” Khashoggi is heard saying. “That friend of mine… maybe he was talking critically over something at a dinner party. That’s what we are becoming in Saudi Arabia, we are not used to that, we never experienced [this],” he added.A delegation from Saudi Arabia has arrived in Turkey for the investigation into Khashoggi’s disappearance, Turkey’s state-run Anadolu Agency reported Friday. Trump rules out immediate action on arms sales US President Donald Trump has said his administration was being “very tough” with Saudi Arabia as it investigates Khashoggi’s case.Trump's Saudi embrace was always complicatedBut Trump said Thursday that he was reluctant to take action, particularly on the issue of arms sales. “There are other things we can do,” he told reporters at the White House.”I don’t like the concept of stopping an investment of $110 billion into the United States because you know what they’re going to do, they’re going to take that money and spend it in Russia or China,” Trump said, referring to a US arms deal with Saudi Arabia. “If it turns out to be as bad as it might be, there are certainly other ways of handling the situation.”The US signed a nearly $110 billion defense deal with Saudi Arabia in May 2017, when Trump made Saudi Arabia a stop on his first foreign trip as president. The stop was seen, in part, as an endorsement of the strong relationship between Trump, Jared Kushner — his son-in-law and senior adviser — and bin Salman.France’s Foreign Ministry said it had demanded that Saudi Arabia provide a “complete and detailed response” with regard to the reported killing of Khashoggi, whose disappearance “raises serious questions about his fate.””France demands that the facts are clearly established,” the ministry said.Gulf Arab states came out in support of Saudi Arabia, however, in the first wave of official reactions from its neighbors.In a tweet Thursday, the United Arab Emirates’ Foreign Minister, Anwar Gargash, called media reports on the matter “a fierce campaign” run in coordination with “inciting parties.””The repercussions of political targeting of Saudi Arabia will be dire on those who inflame it,” he said. Bahrain’s Foreign Minister, Khalid bin Ahmad, said that “Saudi Arabia is the target, not the search for truth.”Turkish investigationSaudi officials had agreed to allow Ankara to inspect the consulate as part of Turkey’s investigation into the missing journalist. But it was not clear Friday whether this inspection had taken place. A senior Turkish official speaking on the condition of anonymity had previously told CNN that “the Saudis are not cooperating fully with the investigation. They are not open to cooperating.”On Friday, a Saudi official said that he “welcomed” an announcement by the Turkish President to form a joint team of experts from both countries to investigate Khashoggi’s disappearance and that he was “fully confident of the team’s ability to accomplish the mission,” according to a statement from the Center for International Communication at the Saudi Information Ministry. He said the “Kingdom attached utmost priority to its citizens’ safety and security, irrespective of their location.”Sabah, a pro-government private newspaper in Turkey, on Tuesday listed 15 names alongside photographs of men who authorities believe were flown into Istanbul from Riyadh. The state-run Anadolu news agency later published similar details on eight of the individuals.One of the Saudi men was identified by Turkey’s official Anadolu Agency and Sabah as Salah Muhammed al-Tubaiqi. He is listed on an official Saudi health website as the head of the forensic medicine department at the interior ministry.
