Cuba is grappling with an escalating fuel crisis exacerbated by stringent U.S. sanctions, which have resulted in widespread shortages and significant disruptions to daily life. The country has reportedly run out of jet fuel, leading to the suspension of flights by several airlines, including Air Canada. The U.N. has condemned the U.S. measures, stating they are deepening the energy crisis and harming essential services like hospitals and education. Meanwhile, Russia is preparing to supply crude oil to Cuba, viewed as humanitarian aid by some, even as it warns of the critical fuel situation on the island. Tourists are leaving Cuba amid the ongoing crisis, which has been described as pushing the nation to the brink of collapse. Various airlines are reevaluating their operations in response to the fuel shortage, and the Cuban government is attempting to manage the fallout as the blockade continues to tighten its grip on the economy.
