President Harry S. Truman’s decision to drop an atomic bomb on the Japanese city of Hiroshima in 1945 was “inhumane and horrific,” Russia claimed on Monday.

“Today marks 73 years since the inhumane and horrific A-bombing of [Hiroshima] — not a military target but a city full of civilians incl[uding] women & children,” the Russian Embassy in South Africa tweeted. “6 August 1945 will forever remain a tragic date in human history. Such tragedy should never be ignored or forgotten.”
