Saudi foreign min: We do not know how Khashoggi was killed or where body is

Comments from foreign minister Jubeir

Saudi Arabia seems to be having a difficult time getting its story straight. In an interview on Fox News, Foreign Minister Jubeir says they don't know how Khashoggi was killed or where the body is.

That contradicts a Saudi statement released on Friday that said he was killed is some kind of brawl at the consulate.

Jubeir says they're working on finding out where the body is and what happened; while saying they will hold those responsible to account. He called the incident "an aberration, a mistake".

On Friday, Trump called the Saudi account 'convincing' but waves of criticism led to a turn on the weekend and he's now accusing them of 'deception' and 'lies' saying he's 'not satisfied' with the explanation.

That increases the likelihood of some kind of US response or sanctions. In turn, it could lift oil prices early in the week. WTI closed Friday at $69.12 and Brent finished at $79.78.

Turkey's Erdogan promised details on the case Tuesday.
