People watch a TV showing a file image of North Korea's missile launch during a news program at the Seoul Railway Station in Seoul, South Korea on July 31, 2019. North Korea fired several unidentified projectiles off its east coast, South Korea's military said, less than a week after the North launched two short-range ballistic missiles into the sea in a defiance of U.N. resolutions. The signs read: "North Korea's missile is a bit different from the past."
