Jamal Khashoggi was suffocated immediately after entering Saudi Arabia's consulate in Istanbul on October 2, the statement added, as it reiterated a request for the extradition of suspects arrested by Saudi Arabia in the case of the brutal murder.
"The victim's body was dismembered and destroyed following his death by suffocation - again, in line with advance plans," AFP quoted Fidan's office as saying in a statement. "Despite our well-intentioned efforts to reveal the truth, no concrete results have come out of those meetings."
According to the statement Khashoggi's killing was "pre-planned and his body parts were disposed off after being dismembered". He was "choked immediately" after entering Saudi Arabia's consulate in Istanbul to get documents for his forthcoming marriage, it said.
Fidan's office said discussions this week with his Saudi counterpart, Saud al-Mojeb, had yielded “no concrete result” despite "good-willed efforts" by Turkey to uncover the truth.

According to the statement, Fidan asked Mojeb about the location of the journalist's body and whether the Saudi investigation had reached any findings regarding plans to kill Khashoggi.
Khashoggi was killed after entering Saudi consulate in Istanbul on October 2. As per 'leaked' reports, days after he was killed inside the consulate, the body parts of the dissident journalist were found at the Saudi consul general's home.
