Tokyo: Japan today marked 71 years since the city of Hiroshima was destroyed by a US atomic bomb, as its mayor urged the world to unite in abolishing nuclear weapons.
The annual ceremony came just months after Barack Obama became the first sitting US president to visit the western Japanese city, paying moving tribute to victims of the devastating bomb.
American B-29 bomber Enola Gay dropped its deadly payload, dubbed "Little Boy", on Hiroshima at 8:15 am local time on 6 August, 1945. Much of the city was incinerated by a wall of heat up to 4,000 C (7,232 F) — hot enough to melt steel — killing tens of thousands.
About 50,000 participants, including Prime Minister Shinzo Abe and representatives of more than 90 countries and regions, observed a minute's silence at the exact time the atrocity occurred some seven decades ago.
During the solemn ceremony, Hiroshima mayor Kazumi Matsui recalled the visit by Obama in his peace declaration, citing the president's historic speech.
"(His visit) was the proof that Hiroshima's strong wish not to tolerate the 'absolute evil' was shared by President Obama," he said. The mayor urged the world to take action towards the abolition of "the ultimate form of inhumanity, united and with
passion". Obama in May embraced survivors as he made his visit to the city and the Hiroshima Peace Memorial Park.
"71 years ago, death fell from the sky and the world was changed," he said of the bomb, adding it "demonstrated that mankind possessed the means to destroy itself". Obama offered no apology for the bombings, having insisted he would not revisit decisions made by then president Harry Truman.
But his moving tribute and brief conversations with elderly survivors, which included an unexpected embrace with one of them, profoundly impressed most Japanese.
Abe, after lying a wreath of flowers, reiterated Saturday that Tokyo will continue working to rid the world of nuclear weapons.
"I am convinced (Obama's visit) brought a great hope for people in Japan, in the world and in Hiroshima and Nagasaki, who believe in a world without nuclear arms," he said.
The bombing claimed the lives of 140,000 people. Some died immediately while others succumbed to injuries or radiation-elated illnesses weeks, months and years later.
A second bomb destroyed the city of Nagasaki three days later. Japan announced its surrender in World War II on 15 August.
