Prime Minister Narendra Modi on Saturday unveiled a statue of iconic Indian freedom fighter Mahatma Gandhi.
"Unveiled Mahatma Gandhi's bust in Hiroshima. This bust in Hiroshima has a very important message. The Gandhian ideals of peace and harmony reverberate globally and give strength to millions," PM Modi tweeted in English and Japanese, along with a photo of the bust.
Speaking to reporters after the ceremony, Modi said: "Even today, the world is frightened when it hears the word 'Hiroshima'."
Hiroshima and Nagasaki in Japan were the first and only targets of nuclear bombings in human history.
On 6 and 9 August 1945, the United States dropped bombs on these cities killing between 129,000 and 226,000 people, according to various estimates.
"The bust of Mahatma Gandhi in Hiroshima will promote the notion of non-violence," Modi said.
"It is great for me to know that the Bodhi tree [Tree of Awakening] that I gave to the Japanese PM has been planted here in Hiroshima so that people can understand the importance of peace when they come here. I pay my respects to Mahatma Gandhi," he added.
