Many atomic bomb survivors, including campaigner Setsuko Thurlow, voiced anger and disappointment at the Group of Seven leaders summit on Sunday after the leaders released a statement that supported the possession of nuclear weapons for deterrence and failed to mention the treaty banning nuclear arms.

Thurlow, 91, called the G7 summit a "huge failure" in the closing hours of the three-day gathering, calling the Hiroshima Vision on Nuclear Disarmament statement issued at the end of the first day "blasphemy against atomic bomb survivors."

Prime Minister Fumio Kishida had billed the gathering in Hiroshima, a city devastated by an atomic bomb, as an opportunity to advocate for a "world without nuclear weapons."
