Saudi dissident journalist Jamal Khashoggi's fiancée has held the Saudi authorities responsible for his recent murder in Istanbul, slamming the United States president for paving the way for Riyadh to cover up the crime.
"This took place inside a Saudi diplomatic mission ... in such circumstances, the Saudi Arabian authorities are responsible for this", she said.
"We know the orders came from a member of the royal circle but have no direct information to link them to Crown Prince Mohammad bin Salman", the article further quoted the source as saying.
"The individuals are Saudi nationals, they are detained in Saudi Arabia, the investigation is in Saudi Arabia", Foreign Minister Adel Al-Jubeir said Saturday at the Manama Dialogue conference in Bahrain.
"President Trump should help reveal the truth and ensure justice be served", Ms Cengiz said through a translator.
Turkish investigators have reviewed thousands of hours of closed-circuit-television footage, taken forensic samples from the consulate grounds and released details of the passports of the 15 Saudis they say were involved.
Turkish President Recep Tayyip Erdogan said Friday that his country would reveal more evidence about the killing but was not in any rush to do so, indicating that Turkish authorities will keep methodically increasing pressure on Saudi Arabia.
He clarified later that the murder and cover-up should have never happened.

The meeting was the first between leaders of the two countries since then-Prime Minister Shimon Peres visited in 1996. Earlier this week, Palestinian President Mahmoud Abbas also visited the Persian Gulf Arab state for three days.
Asked Monday what action the USA has taken nearly four weeks after Khashoggi's disappearance, White House Press Secretary Sarah Huckabee Sanders told reporters that "the administration is considering what action we'll take moving forward" after Haspel gathered more intelligence and briefed the president.
Despite the outcry, Trump has ruled out cutting off arms deals with Saudi Arabia, the biggest importer of weapons from American defence contractors.
Earlier this month U.S. Secretary of State Mike Pompeo met the Saudi king and crown prince to discuss the issue.
The body of Khashoggi, who was once an insider in Saudi royal circles, remains missing. "I want those who killed my beloved Jamal and those who ordered [the killing] to be brought to justice", Cengiz said, speaking at a memorial event held in Westminster.
Turkish prosecutors have prepared a request for the extradition from Saudi Arabia of 18 suspects who were arrested by Riyadh as part of the investigation.
"If only I knew that would be the last time i would see my Jamal, I would have stood in front of that murderous team myself".
The killing has tainted the image of Prince Mohammed, who has positioned himself as a Saudi reformer, and tested ties between Washington and Riyadh as Western powers demand answers over Mr Khashoggi's death. But the decision to marry in Istanbul, whose mosques reminded Mr. Khashoggi of his hometown Medina, set off a paper chase that ultimately ended in death.
Under mounting worldwide pressure, Saudi Arabia has changed its narrative about Khashoggi's killing several times, recently acknowledging that Turkish evidence shows it was premeditated.
