Hiroshima -The atomic bombing on Hiroshima was a criminal, unnecessary and morally-unjustifiable event, the first vice president of Cuba''s Councils of State and of Ministers, Miguel Diaz-Canel, said here on Wednesday.

The Cuban leader, who is on an official visit to Japan until June 3, toured the Atomic Bomb Museum in this city, along with Deputy Foreign Minister Rogelio Sierra, Cuban Ambassador to Japan Marcos Rodriguez-Costa and the delegation accompanying him.

After listening to the explanations and seeing the photos and the remains of the belongings of the victims of the atomic bomb on August 6, 1945, Diaz-Canel said that event is part of a history that humankind must never forget.

He expressed the Cuban government's staunch determination to continue fighting for peace and to achieve a world free of nuclear weapons.

The Cuban vice president noted that no people have to go through what this Japanese municipality suffered. He described the Hiroshima people as historic, due to their resistance and efforts to rebuild their lives after that brutal action.

At the end of the visit to the historic museum, Diaz-Canel signed a book of condolences and dedicated his words to "a people who were capable of surviving and rebuilding and who left a legacy of dignity that humankind must never forget."

He also ratified the phrase written by the historic leader of the Cuban Revolution, Fidel Castro, in 2013, when he said that "such a barbaric event must never happen again".

At a meeting with Mayor Matsui Kazumi, Diaz-Canel expressed gratitude for the opportunity to learn about Hiroshima.

The Cuban people for more than 50 years have been the target of constant aggressions. We share and understand the pain of the victims and relatives of the atomic bombing on Hiroshima, he said.

Diaz-Canel noted that Cuba grants high priority to strengthening, expanding and diversifying political, economic, commercial, financial, cultural and cooperation relations with Japan.

When explaining how Cubans know about the atomic bombing on Hiroshima, he recalled the visit paid to this city by Commander Ernesto Che Guevara in 1959 and by Fidel Castro in 2003.

For his part, Kazumi, who is also the president of Mayors for Peace, called on Cuban municipalities to join that strategy (at present, Havana and Santiago de Cuba are members of the group).

Diaz-Canel's response to that request was affirmative and he signed the book of visitors of the Town Hall of Hiroshima, expressing his interest and that of the Cuban government to further boost relations of all kind with the so-called Land of the Rising Sun.
