I don't know whether this news is true or not. It has got largest chance to have such a price difference, because in the past similar thing happened in India when the fiat that's under usage got demonetized. But during those days such an increased difference wasn't felt.
This can be true because the recent news Zimbabwe reach nearly $10000

Citizens there force to switch to Bitcoin to pay their bills. And that cause massive adoption of Bitcoin there. That's why the price of Bitcoin there was skyrocketed nearly almost $10,000 a piece.
