The Istanbul Chief Prosecutor’s office claimed Wednesday that Saudi journalist Jamal Khashoggi was strangled and then dismembered as soon as he entered the Saudi Consulate in Istanbul.

Khashoggi was a Saudi journalist critical of the royal family who went missing after entering the Saudi consulate on October 2. The Saudis initially denied culpability, but then admitted that the suspects had murdered Khashoggi in a premeditated fashion.

The office of Turkish President Recep Tayyip Erdoğan has demanded that Saudi Arabia turn over 18 suspects complicit in Khashoggi’s death to clear up an “atrocious murder.” Last week, US Secretary of State Mike Pompeo revoked the visas of these suspects, claiming “the United States does not tolerate this kind of ruthless action to silence Mr. Khashoggi, a journalist, through violence.”

A situation which has in a month turned from a curious disappearance to an international murder case has drawn condemnation from international bodies. Last week UN Special Rapporteur David Kaye urged a thorough investigation. “The death of Jamal Khashoggi,” he said, “is emblematic of a broad kind of attack on freedom of information and journalistic reporting.”

Friday marks the International Day to End Impunity for Crimes Against Journalists, observed each year on November 2.
