It comes after claims the state will be able to launch a nuclear-capable intercontinental ballistic missile as early as next year
North Korea has fired a missile which may have landed in Japanese waters.
The rogue state reportedly made the test launch from its northern Jangang province.
The missile may have landed in the sea off North Korea’s east coast – possibly in Japan’s exclusive economic zone, South Korea and Japan said.
The launch took place at 11.41pm (14.41 GMT) , an South Korean government official said.
The US Defense Department also confirmed the launch of a ballistic missile, saying it was making further assessments.
South Korean President Moon Jae-in called a National Security Council meeting for 1am Saturday.
Japanese Prime Minister Shinzo Abe also said a National Security Council meeting would be convened.
The cabinet is expected to do a media briefing shortly.
If confirmed, the latest test would be the 14th missile test conducted by North Korea in 2017.
