Cuba's government on Monday confirmed that a meeting with US representatives recently took place on the island, in the latest sign of a diplomatic approach between both countries amid a severe energy crisis caused by Washington's blockade of oil supplies.

Two US Democratic lawmakers have met Cuba's president in the first congressional visit since Washington imposed an oil blockade against the island.

Cuban President Miguel Díaz-Canel said Thursday that while Cuba does not want military aggression from the United States, his country is prepared to fight should it happen.

U.S. and Cuban officials met in Havana to discuss diplomatic relations and economic reforms amid rising tensions, with both sides addressing military threats and the need for change.
