HAVANA (AP) — Cuba suffered a massive power outage Friday night affecting Havana and the country's provinces that left millions in the dark. Cuba’s Ministry of Energy and Mines said at around 8:15 p.m. local time an outage at the Diezmero substation on the outskirts of Havana had caused “a significant loss of generation in western Cuba and, with it, the failure of the National Electric System.” The ministry said on its account on the social platform X that it is “working on the recovery process.” The streets of Havana were dark and empty, with light coming only from the windows of hotels that had generators. Internet service was affected.
