NEW YORK--Shouting “No More Hiroshima, No More Nagasaki,” hundreds of demonstrators marched through a downpour in New York City on June 17, calling for a treaty to ban nuclear weapons under negotiations at the United Nations.

Atomic bomb survivors and others took turns giving speeches when they arrived at the square near the United Nations headquarters. The 1.5-kilometer march was organized by the Women’s International League for Peace and Freedom.

Elayne Whyte, Costa Rica's ambassador who is chairing the negotiations, pledged to strive toward the establishment of the treaty, while expressing gratitude toward the 3 million signatures collected in a campaign by atomic bomb survivors to highlight the importance of the U.N. talks.

Hibakusha survivors from Hiroshima and Nagasaki traveled to New York to coincide with the negotiations and handed the signatures to Whyte at the U.N. headquarters the previous day.

Toshiyuki Mimaki, 75, a hibakusha from Hiroshima, said he was touched by the participation of so many people in the march.

“Despite the heavy rain, a large number of people came and shouted Hiroshima and Nagasaki together,” said Mimaki. “I am so happy and grateful.”

Rallies were also held across Japan on June 17 to coincide with the New York City march.
