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 price difference is insane. The Zimbabwean will suffer from buying bitcoin at this much too high price while the original price has a difference of almost $5000K. In India there was a price difference but that was not this much high level nor was the bitcoin price this much high. Anyway it doesn't mean that the people buying bitcoin at $12K will face any loses but they will have to wait a little longer to earn profit.
