North Korea's new missile test ended in failure on Wednesday after it exploded a few minutes after its launch, according to South Korea's military. The launch attempt was made from Wonsan, a city on North Korea's east coast. It remains unclear what type of missile it was, as the South Korean defense ministry conducts analysis to obtain further details. The increased frequency of missile tests carried out in the country has sparked concern on how to respond to the state. The test comes only a few days after Secretary of State Rex Tillerson went on an Asia trip to discuss North Korea.
