The recent escalation of the U.S. oil blockade against Cuba has led to severe disruptions in the island nation, affecting its 11 million residents. According to Al Jazeera, the blockade has pushed Cuba to the brink, forcing the government to impose emergency measures amid a fuel crisis. The Guardian reports that Air Canada has canceled all flights to Cuba due to the island running out of aviation fuel, a direct consequence of the U.S. blockade. This has significant implications for Cuba's tourism sector, particularly as Canada is the top source of tourists to Cuba. The New York Times adds that Air Canada had to suspend its 16 flights per week to four Cuban cities, affecting thousands of travelers.
