People watch a television news report showing file footage of North Korea's missile launch at a railway station in Seoul on October 20, 2016. North Korea on October 20 conducted what appeared to be its second failed test in a week of a powerful medium-range missile that experts warn could be operationally deployed as early as next year. South Korean and US military monitors said the missile -- believed to be an intermediate-range Musudan -- exploded shortly after take-off at around 6:30 am Pyongyang time. / AFP / JUNG YEON-JE (Photo credit should read JUNG YEON-JE/AFP/Getty Images)
