North Korea fired a ballistic missile in an unusual late-night test launch from its northern Jangang province.

South Korea and Japan said, the missile landed in the sea off its east coast, possibly in Japan’s exclusive economic zone.

The U.S. Defense department also confirmed the launch as a ballistic missile, saying it was making further assessments.

South Korean President Moon Jae-in called a national security council meeting and Japanese Prime Minister Shinzo Abe also said a national security council meeting would be convened.
