Thousands gathered in Nagasaki on Saturday to mark 80 years since the US atomic bombing that killed tens of thousands in 1945. A moment of silence was held at 11:02 a.m., the time the blast struck, according to Reuters.

Mayor Shiro Suzuki warned that global tensions risk another nuclear disaster and urged world leaders to commit to disarmament. Representatives from 95 countries, including nuclear powers, attended the ceremony.

Survivors, or hibakusha, still face health issues and stigma, but their stories continue to fuel calls for a nuclear-free world. Japan supports disarmament but has not joined the UN treaty banning nuclear weapons, Reuters reported.
