Saudi Arabia deployed a chemist and toxicology expert to Istanbul after the murder of journalist Jamal Khashoggi in an attempt to cover up evidence of the killing, a Turkish newspaper reported on Monday.
While Riyadh officials have admitted the murder was planned, they have so far declined to release details of the whereabouts of the 59-year-old journalist's missing body.
According to Turkey's pro-government Sabah daily, Saudi Arabia sent an 11-member "cover-up team" to Istanbul on October 11, nine days after the Washington Post contributor vanished after entering the diplomatic compound to obtain paperwork for his marriage.
The paper said chemist Ahmad Abdulaziz Aljanobi and toxicology expert Khaled Yahya Al Zahrani were among "the so-called investigative team", which visited the consulate every day until October 17, before leaving Turkey on October 20.
Turkey's chief prosecutor said last week that Khashoggi was strangled as soon as he entered the consulate and also confirmed the body was dismembered. Yasin Aktay, an advisor to Erdogan, hinted in an article published on Friday that the body may even have been destroyed in acid.
In an editorial published in The Washington Post, Erdogan accused authorities in Riyadh of refusing to answer key questions about the murder, despite their arrest of 18 suspects a fortnight ago.
The murder has badly tainted the kingdom's de facto ruler.
