Turkish officials have audio and video evidence that shows missing Saudi journalist Jamal Khashoggi was tortured and killed inside the Saudi consulate in Istanbul, the BBC has learned.
Mr Khashoggi, a critic of the Saudi government, has not been seen since he entered the building on 2 October.
Turkish intelligence had "documented evidence" of the murder, a source close to the investigation said.
Saudi Arabia denies the allegations. It says the journalist left the building.
Jamal Khashoggi's disappearance and reported death have prompted international outrage and dented business confidence in Saudi Arabia. Tycoon Sir Richard Branson has halted talks over $1bn Saudi investment [bbc.com] in Virgin space firms and several top business leaders have pulled out of a Saudi investment conference later this month.
