Answer: North Korea
Notes: North Korea has recently fired three ballistic missiles toward the sea east of the Korean Peninsula, as per the South Korean military. The three short-range ballistic missiles were fired from North Hwanghae Province, south of the capital Pyongyang. The launches came a day after South Korea successfully conducted a test flight of a solid-propellant space launch vehicle. North Korea has fired around 70 ballistic missiles this year, including about eight intercontinental ballistic missiles (ICBM).
