Nagasaki: The Japanese city of Nagasaki on Sunday commemorated the 75th anniversary of its destruction by a US atomic bomb, with its mayor and the head of the United Nations warning against a nuclear arms race.
Nagasaki was flattened in an atomic inferno three days after Hiroshima -- twin nuclear attacks that rang in the nuclear age and gave Japan the bleak distinction of being the only country to be struck by atomic weapons.
Survivors, their relatives and a handful of foreign dignitaries attended a remembrance ceremony in Nagasaki where they called for world peace.
Participants offered a silent prayer at 11:02 am (0402 GMT), the time the second and last nuclear weapon used in wartime was dropped over the city.
"The true horror of nuclear weapons has not yet been adequately conveyed to the world at large" despite decades of effort by survivors telling of their "hellish experience", Nagasaki mayor Tomihisa Taue said in a speech afterwards.
"If, as with the novel coronavirus -- which we did not fear until it began to spread among our immediate surroundings -- humanity does not become aware of the threat of nuclear weapons until they are used again, we will find ourselves in an irrevocable predicament."
UN Secretary General Antonio Guterres, in a message read by his undersecretary Izumi Nakamitsu, warned that "the prospect of nuclear weapons being used intentionally, by accident or miscalculation, is dangerously high".
"The historic progress in nuclear disarmament is in jeopardy... This alarming trend must be reversed," he said.
The number of participants in this year's ceremony was reduced to roughly one tenth the figure in previous years due to coronavirus fears, with proceedings broadcast live online in Japanese and English.
Prime Minister Shinzo Abe refreshed his pledge that Japan would lead "the international community's efforts towards the realisation of a nuclear-free world".
Terumi Tanaka, 88, who survived the Nagasaki bombing when he was 13 at his house on a hillside, remembers the moment everything went white with a flash of light, and the aftermath.
"I saw many people with terrible burns and wounds evacuating ... people who were already dead in a primary school-turned shelter," Tanaka told AFP in a recent interview, saying his two aunts died.
Atomic bomb survivors "believe that the world must abandon nuclear arms because we never want younger generations to experience the same thing", he said.
The remembrance comes as worries linger over the nuclear threat from North Korea and growing tensions between the US and China over issues including security and trade.
The US dropped the first atomic bomb on Hiroshima on August 6, 1945, killing around 140,000 people. The toll includes those who survived the explosion itself but died soon after from radiation exposure.
Three days later, the US dropped a plutonium bomb on the port city of Nagasaki, killing 74,000 people.
Japan announced its surrender in World War II on August 15, 1945.
The United States has never acceded to demands in Japan for an apology for the loss of innocent lives in the atomic bombings, which many Western historians believe were necessary to bring a quick end to the war and avoid a land invasion that could have been even more costly.
Others see the attacks as unnecessary and even experimental atrocities.
Last year, Pope Francis met with several survivors on visits to Hiroshima and Nagasaki, paying tribute to the "unspeakable horror" suffered by the victims.
In 2016, Barack Obama became the first sitting US president to visit Hiroshima. He offered no apology for the attack but embraced survivors and called for a world free of nuclear weapons....
