Cuba's Díaz-Canel warns US

Díaz-Canel's stance comes as the U.S. shifts its focus toward the island nation following the escalation of the war in Iran.

While expressing an openness to dialogue and potential energy investments, he warned that any invasion would be costly and severely destabilize regional security.

Representative Pramila Jayapal, following a recent visit to Cuba, called the U.S. oil blockade 'outrageous' and urged formal negotiations.

The Cuban leadership remains dug in, refusing to commit to U.S. demands for multi-party elections or the release of political prisoners.
