North Korea fired at least one ballistic missile toward Japan early Friday morning, local time, South Korean news agency Yonhap reports. The missile reportedly passed over Japan without striking the country, and landed approximately 1,200 miles east of the coast, Japanese news agency NHK reports. Japan's government advised people to take shelter, and continued to warn of potential debris after the missile passed. "U.S. Pacific Command detected and tracked what we assess was a single North Korean ballistic missile launch at 11:57 a.m. (Hawaii time) Sept. 14," U.S. military officials announced in a statement. "Initial assessment indicates the launch of an intermediate range ballistic missile (IRBM). The launch occurred in the vicinity of Sunan, North Korea and flew east. The ballistic missile overflew the territory of northern Japan before landing in the Pacific Ocean east of Japan."
