Three days after test-launching several short-range projectiles toward the Sea of Japan (known in Korea as the East Sea) from Gwangwon Province, North Korea on Tuesday morning conducted a test launch of a ballistic missile.

Coming less than a week after U.S. Secretary of State Rex Tillerson described a "level of restraint" from Pyongyang in August, Japan's Chief Cabinet Secretary Yoshihide Suga on Tuesday morning described the launch as an “unprecedented, serious, and grave threat to our nation."
