This gives an interesting account of what happened as reported by witnesses.
Seems the Canadian mining executive became involved after taking a decision to try to help others.

If the witness report is correct then he's a very brave guy. I'd go as far as to say hero.
Many other foreign tourists decided not to get involved after being threatened at gunpoint.
