ISTANBUL, Nov. 16 (Xinhua) -- A funeral prayer was held in Istanbul on Friday for the murdered Saudi journalist Jamal Khashoggi.

Around 500 people, including political figures and friends of Khashoggi coming from different parts of the world, gathered in the city's Fatih Mosque to commemorate the slain journalist with a final prayer.

Speaking on the occasion, Yasin Aktay, a senior adviser to Turkish President Recep Tayyip Erdogan within the ruling Justice and Development Party, called for "justice" for the Saudi journalist, who disappeared after he entered the Saudi consulate in Istanbul on Oct. 2.

According to Istanbul chief prosecutor, Khashoggi was strangled to death inside the Saudi mission and then his body was dismembered and destroyed.

On Thursday, Saudi Arabia's public prosecutor demanded death penalty against five of the suspects in the murder of Khashoggi.
