United Nations chief Antonio Guterres cautioned on Saturday about the rising stocks of nuclear weapons, warning that crises with dangerous nuclear overtones were spreading rapidly.

Guterres spoke at a ceremony commemorating the 77th anniversary of the Hiroshima atomic explosion, which killed 140,000 people and devastated two-thirds of the Japanese city.

“Nuclear weapons are nonsense. Three-quarters of a century later, we must ask what we have learned from the mushroom cloud that swelled above this city in 1945,” the UN Secretary-General said at Hiroshima Peace Memorial Park. EFE
