Turkish President Recep Tayyip Erdogan first accused the Saudi government of direct killing journalist Jamal Khashoggi.
"We know that the order to kill Khashoga comes from the highest level in the Saudi government," he wrote in an article in the Washington Post.
But emphasizing Turkey's "friendly" relations with Saudi Arabia, he added that he did not believe King Salman was involved.
Khashoggiot was assassinated in Istanbul on October 2 in the Saudi Consulate.
Turkish researchers believe that an exiled journalist was strangled when he visited his upcoming marriage to Turkish citizens.
His body was not found and President Erdogan's assistant, Yasin Aktay, said he believed it would dissolve after the acidic dissolution.
The murder originally covered by the Saudi officials caused a diplomatic crisis between Saudi Arabia and its allies.
The Saudis have so far suspected 18 suspects who say they are being tried in Saudi Arabia. Turkey wants them to be released.
The memorial commemorating four weeks after the journalist's death has been held in Washington.
What did Erdogan say?
"We know the perpetrators are among the eighteen suspects in Saudi Arabia," wrote the Washington Post, where Khashoggi wrote a column.
"We also know that these individuals have come to execute orders: Kill Khashoggi and leave, and finally we know that the order to kill Khashoga comes from the highest level in the Saudi government."
The fact that the murder was "more than a security officer", President Erdogan called for "exploration of puppet masters following Khashoggi's death."
"Nobody will dare to follow such actions at the NATO ally," he said. "If someone chooses to ignore this warning, he will have serious consequences."
He complained that no action had been taken against the Saudi prosecutor who left Turkey and accused the Saudi prosecution of not cooperating with the investigation, "and even answers simple questions."
What do we know about the murder?
The Saudis acknowledged that Khashoggi died in the consulate while denying that they knew what had happened to his body.
A Turkish prosecutor said at the beginning of the week that investigators believed the journalist was immediately stunned to enter the consulate in a planned murder.
His body was cut up and destroyed "again, in line with the foresight," said Iridan Fidan, Procurator.
Who was Khashoggi?
Once a consultant to the Saudi royal family, Khashoggi was neglected last year with the government and entered the arbitrary exile.
The Saudi government and Mohammed bin Salman Crown Prince have become sharp critics who have launched an ambitious economic and social reform program in the country.
In Washington's Memorial, Daniel Balson, Amnesty International, said the Saudi government must be kept above journalistic deaths.
"It's been too long for the impression that impunity is for them, and that the rules apply to others," he said.
"They believe that the government's criticism will disappear in its diplomatic mission, and people who are righteous will not notice or realize that they are not protesting or protesting, they do not remember it, and they are outraged and will not be forgotten."
