While details regarding the launch are still emerging, Japan’s Coast Guard indicated that the missile may have already fallen, with the possibility of a second launch.

South Korea's Joint Chiefs of Staff said the South Korean and US militaries were analysing the launches. It didn't immediately provide specific flight details, including the number of missiles fired and how far they flew.

The official Korean Central News Agency said Kim visited a factory that produces transport erector launchers, or TELs, without saying when he went or where the factory is. TELs are mobile launch vehicles which give North Korea the ability to move missiles around its territory.

North Korean leader Kim Jong Un said his country has a policy of not hesitating to launch a nuclear strike on a rival if provoked, as he praised troops involved in its recent intercontinental ballistic missile test, state media reported Thursday.
