President Recep Tayyip Erdogan of Turkey laid out on Tuesday the Saudi planning of what he called the “premeditated murder” of the journalist Jamal Khashoggi at the country’s consulate in Istanbul, and demanded that the Saudi suspects face justice in Turkey.
After saying he would reveal “the naked truth” about Mr. Khashoggi’s death, Mr. Erdogan, in his first extended remarks on the case, sketched out the chronology of a broad operation and offered some new details.
The team of Saudi officials that arrived in stages in Istanbul to carry out the killing included generals, he said, and the Saudis conducted reconnaissance in rural areas outside the city where investigators have been searching for Mr. Khashoggi’s remains.
“It is clear that this savage murder did not happen at the drop of a dime but was a planned affair,” Mr. Erdogan said, challenging the official Saudi account that the journalist was accidentally killed in a melee inside the consulate.
The speech made clear that Mr. Erdogan had no intention of dropping a case that has created an international furor, and that he would press the Saudis for an honest accounting of a killing that he pointedly noted occurred inside his country. He posed a series of tough questions, throwing down a challenge to the Saudi leadership.
“Why was the 15-man Saudi team in Istanbul on the day of the murder?” he asked. “On whose orders? We are seeking answers. Why was the consulate not opened to investigators immediately? When the murder was so clear, why were there so many different statements given by Saudis? Why has the body of someone, the killing of whom has been officially admitted, not been found? Who is the local collaborator who disposed of Khashoggi’s body? Saudi must answer all these questions.”
Mr. Erdogan’s much-anticipated address, to the weekly gathering of his party in the Parliament chamber in Ankara, came after more than two weeks of carefully orchestrated leaks to the news media by Turkey that implicated the highest levels of the Saudi government, notably the Crown Prince Mohammed bin Salman, in the death of Mr. Khashoggi on Oct. 2.
Saudi Arabia has said that 18 officials were under investigation in the killing, but Mr. Erdogan said that he would call King Salman of Saudi Arabia and ask that the case be adjudicated in Istanbul, not Riyadh or elsewhere in Saudi Arabia.
The Saudi government maintained at first that Mr. Khashoggi had left the Saudi consulate in Istanbul alive and well before reversing course. Since admitting on Friday that Mr. Khashoggi had been killed inside the consulate, Saudi Arabia has claimed that his death was accidental and that the operation was not authorized by the crown prince.
Turkish and Western intelligence officials and politicians have rejected that account as not credible, and Mr. Erdogan made clear in his speech on Tuesday that he held the same view. Without naming names, he said those responsible, no matter how high-ranking, must be held to account.
Mr. Erdogan largely confined himself to confirming and adding some details to what his government had already leaked to the news media, rather than dropping new bombshells. And he did not mention Turkish officials’ claims that his government has audio and video recordings of the killing, and that Mr. Khashoggi was dismembered with a bone saw in the consulate.
Mr. Khashoggi, 59, was a Saudi who had been close to members of the royal family and to Mr. Erdogan, became a critic of the kingdom as the powerful Saudi crown prince, Mohammed bin Salman, cracked down on dissent. Mr. Khashoggi, who wrote columns for The Washington Post, moved last year to the United States.
His death has badly damaged the reputation of the kingdom and Prince Mohammed, who had held himself out as a leader with plans to reform Saudi Arabia’s economy and society. Shortly before Mr. Erdogan spoke, the Saudis opened a much-anticipated investment conference in Riyadh — though in response to the Khashoggi killing, many government officials and financial leaders from around the world had pulled out of the event.
The scandal has soured relations between Saudi Arabia and the United States — as well as other Western nations — and worsened the already frosty dealings between Turkey and Saudi Arabia, two regional powers.
Hours before Mr. Erdogan’s speech, the newspaper Sabah, which is known for its close ties to the presidency, published details that portrayed the attaché of the Saudi Consulate in Istanbul, whom they named as Ahmad Abdullah al-Muzaini, as the main orchestrator of the murder. Mr. Muzaini, the deputy head of the consulate, was the main Saudi intelligence representative there, the newspaper reported, citing Turkish officials.
Mr. Muzaini, the Saudi attaché, was at the consulate when Mr. Khashoggi visited it on Sept. 28; flew later that day to the Saudi capital, Riyadh, and met with the deputy chief of Saudi intelligence, Ahmad Asiri; and returned to Istanbul on Oct. 1 to carry out the assassination the next day, Sabah reported.
The newspaper described Mr. Muzaini as the “black box” of the operation,” and said his movements had been tracked by Turkish intelligence and photographic evidence gathered by the police.
The report was another in a steady stream of anonymous leaks and public statements from Turkish officials over recent weeks that pointed to a premeditated plan at the highest levels of the Saudi government to kill Mr. Khashoggi, undermining Saudi denials and keeping up international pressure on the kingdom to come clean.
On Monday, the Turks leaked images of a Saudi official who resembled Mr. Khashoggi and dressed in his clothes after he was killed, walking around Istanbul, creating a trail of surveillance camera images that appeared to have been intended to support the original Saudi narrative. Saudis briefed on the matter confirmed the ruse.
The use of a look-alike bolstered the Turkish case for premeditation, and at the least, showed an attempt to cover up the killing. On Monday, the spokesman for Mr. Erdogan’s Justice and Development Party, Omer Celik, described the death of Mr. Khashoggi as “monstrously planned.”
Mr. Khashoggi went to the consulate on Sept. 28 to request documents confirming his divorce, so that he could marry his fiancée. Sabah reported that at 2 p.m. that day, Mr. Muzaini flew out of Istanbul’s second airport, Sabiha Gokcen International Airport.
Mr. Khashoggi was killed on Oct. 2 after he returned to the consulate, about 1:15 p.m., to pick up the paperwork he had requested. Mr. Muzaini flew out of Ataturk Airport at 9 p.m. that night, Sabah said.
A team of 15 Saudis who flew to Istanbul on the day Mr. Khashoggi died, several of them with ties to the crown prince, have been identified by Turkish officials as being involved in the killing. They all left the country hours after they had arrived.
