A Canadian airline suspends flights to Cuba as U.S sanctions and Trump's tariff threats force Havana to warn carriers there's no way to refuel on the island.

The longstanding alliance between Cuba and Mexico is under mounting pressure from the United States, forcing President Claudia Sheinbaum into a precarious balancing act.

Canada’s largest airline has said it is suspending flights to Cuba due to a shortage of aviation fuel on the island – a move that comes amid a US orchestrated squeeze on the country’s oil supply that has also forced Havana to ration health,

Cuba's jet fuel shortage is disrupting air travel, with airlines canceling flights, adding refueling stops, and sending empty planes to collect passengers.

Air Canada said it was suspending service to Cuba from Monday due to a lack of guaranteed fuel supply at airports in the country, where US pressure has created an oil crisis. Air Canada said in a statement that "aviation fuel will not be commercially available at the island's airports" as of Tuesday.

"The way to win the war is to avoid it," Cuba's UN ambassador told Newsweek, quoting late President Fidel Castro.

The Trump administration, which has tightened the U.S. chokehold on Cuba by cutting off foreign oil, is betting that this is the Cuban communist revolution’s last year.

The Canadian government’s recent warnings about resource shortages in Cuba has some P.E.I. residents changing their plans to travel to the popular destination — while Islanders who are already in the Caribbean nation are worried for its people and economy.

Cuba's president is offering to hold talks with the U.S. without preconditions, even as both nations exchange warnings.
