A visitor walks by the TV screen showing a news program reporting about North Korea's missile firing, at Seoul Train Station in Seoul, South Korea, Monday, March 6, 2017. North Korea on Monday fired four banned ballistic missiles that flew about 1,000 kilometers (620 miles), with three of them landing in Japan's exclusive economic zone, South Korean and Japanese officials said, in an apparent reaction to huge military drills by Washington and Seoul that Pyongyang insists are an invasion rehearsal. The letters on the top read " North Korea, Fire missile." (AP Photo/Lee Jin-man)
