Cuba's government on Wednesday delayed a planned 500 percent surge in the fuel price after a "cybersecurity incident," an economy ministry official said.
The communist island's cash-strapped government had announced the five-fold increase with effect from February 1, as part of a series of measures seeking to cut its budget deficit.
Economy ministry official Mildrey Granadillo said there had been a "cybersecurity incident ... whose origin has been identified as a virus from abroad."
She did not give a new date for the planned increase.
