NAGASAKI, Japan, Aug 9, (AP): The southern Japanese city of Nagasaki on Saturday marked 80 years since the U.S. atomic attack that killed tens of thousands and left survivors who hope their harrowing memories can help make their hometown the last place on Earth to be hit by a nuclear bomb. The United States launched the Nagasaki attack on Aug 9, 1945, killing 70,000 by the end of that year, three days after the bombing of Hiroshima that killed 140,000.

Japan surrendered on Aug 15, 1945, ending World War II and the country’s nearly half-century of aggression across Asia. About 2,600 people, including representatives from more than 90 countries, attended a memorial event at Nagasaki Peace Park, where Mayor Shiro Suzuki and Prime Minister Shigeru Ishiba spoke, among other guests.

At 11:02 am, the exact time when the plutonium bomb exploded above Nagasaki, participants observed a moment of silence as a bell rang. Dozens of doves, a symbol of peace, were released after a speech by Suzuki, whose parents are survivors of the attack. He said the city’s memories of the bombing are "a common heritage and should be passed down for generations” in and outside Japan.

"The existential crisis of humanity has become imminent to each and every one of us living on Earth,” Suzuki said. "In order to make Nagasaki the last atomic bombing site now and forever, we will go hand-in-hand with global citizens and devote our utmost efforts toward the abolition of nuclear weapons and the realization of everlasting world peace.”

Survivors and their families gathered Saturday in rainy weather at Peace Park and nearby Hypocenter Park, located below the bomb’s exact detonation spot, hours before the official ceremony. "I simply seek a world without war," said Koichi Kawano, an 85-year-old survivor who laid flowers at the Hypocenter monument decorated with colorful paper cranes and other offerings.

Aging survivors and their supporters in Nagasaki now put their hopes of achieving nuclear weapons abolition in the hands of younger people, telling them the attack is not distant history, but an issue that remains relevant to their future. "There are only two things I long for: the abolition of nuclear weapons and prohibition of war,” survivor Fumi Takeshita said. "I only see a world where nuclear weapons are never used and everyone can live in peace.”
