Cuba's electrical grid collapsed for the fourth time in 48 hours, exacerbating an ongoing power crisis as Hurricane Oscar made landfall on the island. The initial blackout began on Friday due to the shutdown of the largest power plant, leaving around 10 million residents in darkness. Protests erupted across the country, with citizens expressing their frustrations through 'cacerolazos,' or pot-banging demonstrations. Cuban President Miguel Diaz-Canel urged calm during a televised address, emphasizing the need for civility amidst the unrest. As the storm threatened to impede restoration efforts, schools were canceled, and only essential workers were advised to report to work. The government acknowledged the precarious state of the electrical infrastructure, which has been plagued by shortages of food, medicine, and fuel.
