To the latest on the investigation over the death of Saudi journalist Jamal Khashoggi. Turkey is demanding the extradition of more than a dozen Saudi suspects in the case. On Thursday, Riyadh admitted the killing was premeditated. Khashoggi was last seen entering the Saudi consulate in Istanbul more than 3 weeks ago. CGTN's Michal Bardavid reports from Istanbul.

"Turkey's Justice Ministry has announced it has put in an official request of extradition for the 18 Saudi that have been arrested in relation to the Khashoggi case. Let's listen to more of what Erdogan had to say."

RECEP TAYYIP ERDOGAN TURKISH PRESIDENT "The fact that he was killed is now evident. But where is he? You need to show his body. It is not that we don't have any other information or documents -- we do. Tomorrow is another day."

"It's also been announced that Saudi Arabian public prosecutors will be travelling to Turkey on Sunday and meet with a Turkish public prosecutor, so it's going to be important to see whether or not this will result in any more admission of guilt by Saudi Arabia. Meanwhile, the fiancee of Khashoggi, Hatice Cengiz, gave her first live interview of Turkish media. She was the one who was waiting outside of the consulate the day that he was killed. She was the one who notified authorities that she was concerned when he didn't leave the consulate afterwards. She also stated Khashoggi himself was concerned the day that he entered the consulate.

HATICE CENGIZ JAMAL KHASHOGGI'S FIANCEE "The fact that he said he didn't want to go -- especially after he had settled in the United States -- a majority of his friends those who were arrested after he left the country. I know he had questions in mind about whether something untoward could actually happen at the consulate."

MICHAL BARDAVID ISTANBUL "Hatice Cengiz also stated that she had no intention of travelling to the United States despite an invitation by US President Donald Trump. She also added that she found Trump's comments to be insincere and contradictory. Michal Bardavid for CGTN in Istanbul."
