Korea's military

North Korea fired a ballistic missile over Japan's northern Hokkaido island into the sea early on Aug. 29, prompting warnings to residents to take cover and drawing a sharp reaction from Japanese Prime Minister Shinzo Abe.

North Korea has launched several unidentified ground-based projectiles, assumed to be surface-to-ship cruise missiles, South Korea's Joint Chiefs of Staff announced.

North Korea fired four ballistic missiles into the sea off Japan's northwest on March 6, angering South Korea and Japan, days after it promised retaliation over U.S.-South Korea military drills it sees as a preparation for war.

North Korea fired what appeared to be a submarine-launched ballistic missile (SLBM) on April 23 off its east coast, South Korea said, amid concerns that it might conduct a nuclear test or a missile launch ahead of a key ruling party meeting in May.
