More than 10 million people have had power cut to their homes and businesses across Cuba after the country's national electrical grid collapsed for the second time in a week. Cuba's energy ministry announced a total disconnection of the National Electrical System in a social media statement. According to the grid operator UNE, efforts are being made to gradually restore electricity, prioritizing essential services like hospitals and water supplies. By Sunday afternoon, about half of Havana had regained power. This month alone, Cuba has experienced three major blackouts, attributed to a fuel blockade from the U.S. that has diminished vital oil imports needed for power stations. As the crisis continues, protests have erupted in various cities, with locals expressing frustration over the ongoing shortages and economic difficulties. A coalition of international socialist groups is set to arrive in Havana to provide aid, while Cuban officials reiterate the country's readiness to defend itself against any external threats, including potential military aggression from the U.S. Recent talks between the American and Cuban governments are aimed at addressing the crisis, but significant tensions remain over the political situation.
