Forensic teams look for evidence after Khashoggi disappearance

In Istanbul, forensic teams have been looking for evidence after the disappearance of Jamal Khashoggi, the Saudi journalist. Turkish officials say they believe he was killed during his visit to the Saudi consulate just over two weeks ago.  Now several news outlets – in Turkey and the US – have reported the existence of audio tapes which they say prove this.  The Saudi Consul General, who’s gone back to Riyadh, says he has no idea what happened to Mr Khashoggi.
