Hundreds of Spaniards demonstrated today to reject a potential U.S. military intervention against Cuba, while reiterating their condemnation of the White House’s economic stranglehold on the island.

Gathered in front of the Cuban Embassy in Madrid, solidarity activists spoke out against the Washington-imposed blockade, which has been intensified by preventing other nations from exporting fuel to the Caribbean nation, in addition to numerous other restrictions.

In what they described as an attempt at a literal siege of Cuba, the group also deplored the inclusion of the Caribbean nation on the list of countries that, according to the Trump administration’s perspective, allegedly sponsor terrorism.

Araceli Escudero, a leader of the State Coordinating Committee for Solidarity with Cuba in Madrid, told Prensa Latina that the initiative seeks to denounce U.S. harassment of the island, which is going through a critical period.

“We want the United States to leave Cuba alone once and for all, and to lift the fuel siege. We are against the blockade, against the inclusion on that list, because Cuba is a country that has been resisting for a very long time,” she said.

Escudero, who is also a member of the Bolivarian Solidarity Platform in Spain, noted that after the military intervention in Venezuela on January 3 of this year, “what we want is for them not to dare try the same with Cuba, to lift the entire fuel blockade, and to let the Cuban people live.”

“We stand with Cuba and will do everything possible to accompany this heroic nation so that an invasion does not happen,” she added.

She pointed out that solidarity and friendship groups with Cuba in Spain are also “asking for the backing of governments, because Russia has been the only country to send a fuel tanker, which has a limited duration.”

Diplomats from the Cuban Embassy in the Spanish capital later stepped out of the legation to thank the demonstrators for their support of the island and their rejection of the U.S. actions of asphyxiation.
