As Saudi Arabia's government officials struggle to explain the circumstances around the killing of Jamal Khashoggi in the country's Istanbul consulate.

Turkish President Tayyip Erdogan has suggested that he's going to release details about the Turkish investigation Tuesday (October 23).

World leaders are continuing to push for more information, after Saudi officials put forth multiple and conflicting accounts about Khashoggi's fate.

One that he died during a fist fight, another in a chokehold.

Turkish sources say the authorities have an audio recording purportedly documenting Khashoggi's torture and murder.

Local media says the Turkish investigation is now focusing on 45 consulate workers, and that several have already given witness statements.

The world is waiting for hard evidence.

U.S. Treasury Secretary Steven Mnuchin labeled the admission he was killed in a fist fight "a good first step but not enough," adding though that it's still premature to discuss sanctions against Riyadh.

Not too soon though for Germany's leader.

Chancellor Angela Merkel saying she wants other EU states to follow its example in stopping arms exports to the kingdom as long as uncertainty over the killing remains.

The Saudi foreign minister has called Khashoggi's killing a "huge and grave mistake".

The bottom line from Riyadh is that whatever happened neither the Saudi King or Crown Prince Mohammed Bin Salman were aware.

Both have called the journalist's son to send their condolences.

Turkish president Erdogan has remained largely silent on the case, but is now expected to address the investigation at his weekly speech.

No body has yet been found, and Turkish authorities have Khashoggi's fiancé under 24-hour police protection.
