Japan issued a temporary shelter-in-place alert after North Korea test-fired another ballistic missile late Thursday, according to Japanese and South Korean news reports. The missile was launched from around the North Korean capitol, Pyongyang, and flew eastward over the northern Japanese island of Hokkaido around 7 a.m. local time, according to NHK. The missile splashed into the Pacific Ocean, and no damage or injuries in Japan were reported. North Korea previously fired a ballistic missile over northern Japan on Aug. 28. This is the rogue nation's 13th missile test this year. Earlier Thursday, North Korea issued new threats, calling to "reduce the U.S. mainland into ashes" and saying Japan "should be sunken into the sea by the nuclear bomb."
