Cuba has suffered a second nationwide blackout in five days amid a fuel shortage resulting from the US energy blockade targeting the Latin American island state.
Cuban National Electric Union said on X on Friday that the country's national power system completely collapsed at 4:30 pm local time, resulting in a nationwide grid power outage.
The blackout cut off the electricity supply to end users.
Friday's complete power failure followed the total outage in Cuba's national power system that occurred on Monday.
Power authorities had reconnected most of the nation's grid from that outage by late Tuesday.
Cuban National Electric Union said on Wednesday that all provinces had been reconnected to the national grid early that day and that electricity supply had been restored nationwide.
The Latin American island state has experienced several nationwide blackouts due to power facility failures, hurricanes and other factors.
