Buildings began to lose power in Havana before nightfall, shortly before 6:30 pm (2230 GMT) and just five days after the previous one plunged the country into darkness.

A "total disconnection" of the national electricity system took place, the Energy Ministry said in a post on X, adding that work had begun to restore power.
