HAVANA, Cuba, Feb 21 (Reuters) - Cuba on Tuesday suffered its third major blackout in little more than a week, leaving a vast swath of the center and east of the island without power, energy officials said on state-run TV.
The blackout Tuesday spanned 430 miles (700 km) from Cienfuegos province in south-central Cuba to Guantanamo, on the far southeastern tip, leaving more than half of the country´s population of 11 million without power.
On Saturday, another blackout cut power for millions of people from Matanzas, east of Havana, to Guantanamo, an outage power officials attributed to a "human operation error."
The Minister of Energy and Mines said last week that rolling blackouts would resume and last until May while the country overhauls decades-old oil-fired power plants ahead of the summer season.
