Erdogan asked the rival government to hand over the Saudi suspects in the case, and said that he would reveal “the naked truth” about Khashoggi’s death. This is the latest in a string of Turkish reports alleging foul play on the part of the Saudi government, indicating that the government is not inclined to let the case fall by the wayside amidst international furor.

According to Erdogan, a 15-member team of top Saudi officials arrived in stages in Istanbul to carry out the murder earlier this month, including generals, senior intelligence officers and forensic officials. Reconnaissance operations were allegedly planned in the surrounding rural areas of Belgrad Forest and Yalova, where investigators have been searching for the journalist’s remains.

“It is clear that this savage murder did not happen instantly but was planned,” Erdogan said, challenging the official Saudi account.

Government representatives in Saudi Arabia have said the murder of journalist Jamal Khashoggi was committed by rogue killers and a “tremendous mistake.” They have sworn they would capture those responsible and bring them to justice. Currently 18 officials are under investigation.

The Turkish president has called on King Salman bin Abdulaziz directly to address the situation, pointedly leaving out the Crown Prince, whom some think is suspect. He also asked that the case be adjudicated in Istanbul, not in Riyadh or elsewhere in Saudi Arabia.

“This murder might have been committed at a consulate building which may be considered Saudi Arabian land, but it rests within the borders of Turkey,” he said. He later added that international agreements on the status of consular property “cannot allow the investigation of this murder to be concealed behind the armor of immunity.”

Erdogan’s widely-anticipated speech is timed to coincide with this week’s showy Future Investment Initiative in Riyadh. The ‘Davos in the Desert’ conference had U.S. government officials and western chief executives deciding not to attend, such as JPMorgan Chase’s Jamie Dimon and Goldman Sachs partner Dina Powell, due to pressure over Khashoggi’s death. Still others are in attendance, like PepsiCo Vice Chairman Mehmood Khan.

While careful not to insult King Salman, Erdogan made the argument that the investigation should be conducted by those with more distance from the crime. “I do not doubt the sincerity of the Custodian of the Two Holy Mosques, King Salman bin Abdulaziz,” he said. “Still, such a critical investigation should be conducted by a fair committee which has no tiniest doubt of connection to the murder.”

Outstanding questions still remain, including why the Saudi consulate building had not been opened until days after the killing, why the Saudis have made many inconsistent statements involving the case, and ultimately—why is the body still missing?

President Trump commented on the Saudi Arabian account of events on Tuesday, calling it “the worst cover-up ever.” He told reporters his final judgement on the case would be reserved until C.I.A. director Gina Haspel returned from Turkey by the end of the week.
