She investigated Jamal Khashoggi’s murder. Now UN official says America must reveal what it knows

There is a recording of a murder. Agnes Callamard has listened to that 15 minutes, in which Saudi journalist Jamal Khashoggi is suffocated and strangled in his country’s Istanbul consulate. She has heard the strange low humming that comes once the voices have stopped that experts believe is the sound of a buzzsaw, being used to dismember the body of a 59-year-old.

Callamard, who investigated the death for the UN, is one of just a few people to have listened to that recording but, though she has heard the moment Khashoggi was killed, many of the details surrounding those 15 minutes remain a mystery, two and a half years on.

Turkish prosecutors and the US intelligence community have alleged that the murder was ordered by Saudi’s crown prince, an allegation adamantly rejected by Mohammed bin Salman (MBS). Now Callamard says she believes the US government still holds information about the killing that could help bring accountability to those responsible.
