Airlines from as far away as Russia, China and Spain have also been affected as island nation warns of fuel shortage

Air Canada has cancelled all flights to Cuba after the island’s authorities said they were running out of aviation fuel, as a consequence of the US oil blockade on the Caribbean country.

The airline, one of a dozen who serve the island, said it would begin repatriating 3,000 customers. Cuba’s beaches are a major holiday draw for Canadian tourists in winter, and one of the government’s most important sources of hard currency.
