South Korean and U.S. officials have confirmed that North Korea has launched another ballistic missile into the sea of Japan. The ballistic missile test -- launched just after 3am Wednesday local time from Sin-ni in South Pyongyang -- is the first since an intermediate-range missile test in September. Ars Technica reports: In a statement to the press, a spokesperson for South Korea's Joint Chiefs of Staff said, "North Korea fired an unidentified ballistic missile early this morning from Pyongsong, South Pyongan [Province], to the east direction. South Korea's Joint Chiefs of Staff is analyzing more details of the missile with the U.S. side." The U.S. Department of Defense and the North American Aerospace Defense Command (NORAD) have made an initial assessment that the missile was an ICBM, according to Office of the Secretary of Defense spokesperson Col. Robert Manning. The missile traveled 1,000 kilometers, flew over Japan, and landed in the sea east of Japan within its exclusive economic zone.
