Havana, August 6 (RHC)-- Cuban President Miguel Diaz-Canel recalled this August 6, the U.S. atomic bombings on the Japanese cities of Hiroshima and Nagasaki, 74 years ago.

The attacks were carried out on August 6 and 9, 1945, respectively, with more than 450,000 people killed immediately by the attacks and as a consequence of diseases generated by nuclear radiation.

” Humanity should not forget this horrible event of history hatched by imperial arrogance, its criminal weapons, its nuclear race and despise for the peoples. No to genocide and imperial barbarity,” wrote President Diaz-Canel on Twitter.

Faced with Japan's refusal to accept the surrender proposal made by the Allied powers in the context of World War II, U.S. President Harry S. Truman authorized the atomic bombing of Hiroshima.   The Little Boy bomb exploded a cargo of 15,000 tons of TNT and devastated a range covering 13 square kilometers.

Three days later, a second atomic device, named Fat Man by the U.S. military, was to be launched over the city of Kokura, but climate problems forced the plan to be executed over Nagasaki.

Six days later, Japanese Emperor Hirohito officially announced a surrender on September 2, 1948.
