North Korea launched a series of short-range ballistic missiles toward the East Sea early Tuesday morning, an act confirmed by military sources in South Korea and Japan just hours before the United States began its presidential elections.

North Korea fired two short-range ballistic missiles into its eastern sea, South Korea's military said Tuesday, adding to a recent streak in weapons testing that is apparently in protest of the U.S. sending major naval assets to South Korea in a show of force.
