Cuban authorities have warned foreign airlines that the country has run out of fuel, and that planes cannot refuel if they land in the island nation.

The fuel shortage was announced Sunday in a notice to airlines flying to Cuba, sources told the AP, and will primarily affect long-haul flights from Russia and Canada. Air Canada also became the first major carrier to announce it was halting flights to the island.

The shortage is blamed on US sanctions, which have caused an energy crisis in the authoritarian country. Over the weekend, crisis measures such as a four-day workweek for staff at state-owned companies were introduced.

US President Donald Trump has threatened punitive tariffs on countries that supply Cuba with oil and specifically called on Mexico to cease its oil exports to Cuba.
