Pope Francis on Monday said he is “truly afraid” of an imminent nuclear war, warning that the world is “at the very limit.” “I am truly afraid of this. One accident is enough to precipitate things,” he told reporters as he departed for a visit to Chile and Peru. The pontiff did not single out any countries in particular, but his warning came after a false missile alert in Hawaii triggered panic on Saturday. Residents frantically texted their loved ones goodbye and went fleeing for shelter, fearing a nuclear attack by North Korea. Authorities later said the erroneous warning had been sent out in error.
