United Nations Secretary General Antonio Guterres has issued a so-called red alert to the world.
Speaking in his year-end address, the former Portuguese prime minister warned of deepening conflicts and raised anxieties about nuclear weapons.
After a year on the job, he said that the world had "gone in reverse."
