Cuba’s national electric grid collapsed again on Tuesday, with the energy ministry reporting a “total disconnection” affecting the island of about 10 million people. The blackout is the third major outage in nine days, compounding already frequent power cuts. Officials link the persistent failures to a severe fuel shortage that has crippled the aging power infrastructure, while blaming U.S. actions that limit oil supplies to Cuba. The latest collapse has fueled mounting frustration over unreliable electricity and shortages tied to the grid breakdown.
