(FILES) People display images of Cuban former president Fidel Castro during the May Day parade at Revolution Square in Havana, on May 1, 2016. As Cuba marks the centenary of Fidel Castro's birth, many Cubans are questioning the promises of the socialist revolution he led for nearly half a century and whether his successors can meet the country's challenges. While Cuba's Communist Party has marked the anniversary with exhibitions, concerts and conferences, August 13, 2026, comes amid one of the island's worst economic crises in decades, with shortages of food and water and chronic power cuts.
