Saudi Arabia has admitted Jamal Khashoggi was killed inside its consulate in the Turkish city of Istanbul.

Khashoggi was a Saudi writer, US resident, and Washington Post columnist. He entered the building on October 2 to obtain documentation certifying he had divorced his ex-wife so he could remarry.

After weeks of repeated denials that it had anything to do with his disappearance, the kingdom eventually acknowledged that the murder was premeditated. The whereabouts of his body are still unknown.

On Monday, October 29, Khashoggi’s fiancee spoke at a memorial in London, where she called for justice.

Hatice Cengiz, Khashoggi’s fiancee, has addressed a memorial for the slain journalist in London.

The event in the British capital was attended by politicians, journalists and activists.

Cengiz said Khashoggi “felt it was his duty to be the voice of the voiceless”, before repeating her demand for justice to be served.

“I want the role of the political leadership in this brutal killing to be brought to light. I want justice for Jamal,” she told the crowd.

“I call upon the conscience of humanity and the international community, please help us to reveal the truth and hold the perpetrators and their masters to account for their crimes.

“I want to bury the body of the beloved Jamal. Therefore I am asking once again, where is his body? I believe that the Saudi regime knows where his body is. They should answer my demand. For this is not only the demand of a fiancee, but a human and Islamic demand from everyone, every nation.

“I want justice to be served. Not only for those who murdered my beloved Jamal, but for those who organised it and gave the order of it. These questions are not just my questions, they are now being asked by millions.”

Last week, speaking to Turkish media, Cengiz said she had declined an invitation by the White House, saying she perceived US President Donald Trump’s move to be “a statement to win public favor”.

During her speech in London, Cengiz said: “President Trump should help reveal the truth and ensure justice be served. He should not pave the way for a cover up of my fiancee’s murder. Let’s not let money taint our conscience and compromise our values.

“There should be no cover-up. Jamal was my beloved fiancee, but he was also a gentle human being, a loving man, a journalist and true believer in freedom and democracy in the Arab world. Let’s demand justice for Jamal and stand up for his ideals.”
