US and Turkish officials told The Washington Post there are audio and video recordings proving Khashoggi was tortured and murdered inside the Saudi consulate in Istanbul.

Video recordings show a Saudi assassination team seizing the journalist after he walked in on October 2. He was then killed and his body dismembered, the officials told the Post - the newspaper that Khashoggi wrote for as a columnist.

The audio was particularly gruesome, the sources said.

"The voice recording from inside the embassy lays out what happened to Jamal after he entered," said one official speaking anonymously because the intelligence is classified.

"You can hear his voice and the voices of men speaking Arabic. You can hear how he was interrogated, tortured, and then murdered."

Another unnamed official confirmed men could be heard beating Khashoggi on the recording.

It was unclear how the Turkish and American officials obtained the recordings.

Recall that Saudi journalist Jamal Khashoggi entered Saudi Arabia's consulate in Istanbul on October 2 to obtain a document certifying he divorced his ex-wife, and has not been seen since then. (Aljazeera)
