The audio recording in particular provides some of the most persuasive and gruesome evidence that the Saudi team is responsible for Khashoggi’s death, the officials said.

“The voice recording from inside the embassy lays out what happened to Jamal after he entered,” said one person with knowledge of the recording who, like others, spoke on the condition of anonymity to discuss highly sensitive intelligence.

“You can hear his voice and the voices of men speaking Arabic,” this person said. “You can hear how he was interrogated, tortured and then murdered.”

A second person briefed on the recording said men could be heard beating Khashoggi.
