Saudi Arabia's King Salman will embark on a week-long domestic tour on Tuesday, a senior government official told Reuters, as the absolute monarchy faces its worst political crisis in a generation over the murder of journalist Jamal Khashoggi.
The Saudi officials tried to rip out a camera inside the Istanbul consulate on October 2, the day Khashoggi disappeared, and days later tampered with cameras at a police security booth in the building, Al-Jazeera reported, citing Turkish media.
Cavusoglu said Tuesday that after multiple conversations with Saudi King Salman, Turkish President Recep Tayyip Erdogan is convinced the king was not involved.
Both Turkish and Saudi officials are investigating the killing.
The two individuals carried out clean-up operations at the consulate and the consul's residence in Istanbul until October 17 and left the country three days later, he said.
As the eldest brother, Salah has been made the point person by Saudi authorities, and the strain of that along with receiving calls from all of Khashoggi's relatives shows in his deeply sunken eyes.
They include 15 members of an alleged Saudi "hit squad" that Turkey says was sent to Istanbul to kill the Washington Post columnist, who had written critically of Saudi Arabia's Crown Prince Mohammed bin Salman.
Ankara has also demanded Riyadh cooperate in finding Khashoggi's body, which Istanbul's chief prosecutor said had been dismembered. Turkey wants the suspects extradited but Saudi Arabia has maintained they will be prosecuted nationally.
Saudi officials have been forced to admit that the death of Mr Khashoggi was "premeditated" after pressure continued to mount from Turkish officials.
Speaking on Monday in Geneva, the president of Saudi Arabia's human rights commission, Bandar al-Aiban, vowed a full investigation and punishment of those responsible, but shed no new light on the case.
Son - whose company has heavily invested in real estate companies like WeWork, Katerra and Lemonade -condemned the attack, but said his company has a "responsibility" to continue to invest the Saudis' funds. The newspaper alleged that while the Saudi team's declared intent was to investigate the murder, it actually meant to cover-up the deed.
The Khashoggi case has worsened Saudi relations with not only Turkey, but also with the United States and some of its closest allies, particularly in Europe.
But the Saudis tweeting their support for crown prince Mohammed bin Salman believe the worldwide media coverage of Khashoggi's death is biased.
