ANKARA, Oct. 11 (Xinhua) -- Turkey and Saudi Arabia agreed to set up a joint team to investigate the disappearance of Saudi journalist Jamal Khashoggi, Turkish presidential spokesman Ibrahim Kalin said Thursday.

Kalin told reporters that the agreement was reached upon Riyadh's request.

"A joint working team between Turkey and Saudi Arabia will be formed to investigate the case in all its aspects," he said.

Khashoggi, a journalist and columnist for The Washington Post, has been missing since he entered the Saudi consulate in Istanbul on Oct. 2 to get documents for his marriage.

Turkish prosecutors have launched a probe into the whereabouts of the Saudi journalist.

Turkish police said that 15 Saudis, including several officials, arrived in Istanbul on two planes and entered the consulate while Khashoggi was inside.

Eight out of the 15 suspects linked to the missing Saudi journalist have been identified by Turkish police.

Unconfirmed reports said that Khashoggi was likely killed inside the compound, which was dismissed by Saudi authorities as "baseless".

Saudi Arabia on Tuesday invited Turkish experts and officials to visit the consulate after Turkey demanded to search the building.
