Iran Press/Middle East: The UK-based rights body made the demand on Thursday during a ceremony outside the Saudi consulate in Istanbul where the incident took place last October to mark 100 days since the murder, Iran Press reported.
"We once again call for an international investigation under the authority of the United Nations into the murder of Jamal Khashoggi," Amnesty's Turkey representative Goksu Ozahishali said.

The Washington Post columnist, who would regularly bash Saudi Crown Prince Mohammed bin Salman in his articles, entered the diplomatic mission to obtain documents for a pending second marriage, but never came out alive.
Murder site dubbed 'Khashoggi Street'
Amnesty activists on Thursday symbolically hung a street sign reading "Jamal Khashoggi Street" where the consulate is located.
"It's absolutely shocking that 100 days later there are no real concrete steps to bring this murder to justice," Andrew Gardner, Amnesty's Turkey strategy and research manager, told AFP.
"Unfortunately, the international community has been incredibly weak, and trade and diplomatic relations with Saudi Arabia have taken precedence over fundamental human values," he said.
Evidence has shown that the killing was carried out by a hit squad with close links to Mohammad bin Salman, and Turkish officials have blamed the royal for the death.
Earlier on January 3, Saudi Arabia's attorney general confirmed that the Kingdom's court held its first secret trial in Riyadh for 11 suspects involved in the Jamal Khashoggi murder case.
Attorney General, Saud Al Mujeb added 11 suspects were indicted in court on Thursday, according to Saudi media outlets.
During the court session, the prosecutor asked for death sentences to be handed to five suspects accused of killing journalist, Jamal Khashoggi.
