The United Nations chief has warned the world that “humanity is just one misunderstanding, one miscalculation, away from nuclear annihilation”.

Secretary-general Antonio Guterres gave the dire warning at the opening of the long-delayed high-level meeting to review the landmark 50-year-old treaty aimed at preventing the spread of nuclear weapons and eventually achieving a nuclear-free world.
