North Korea to launch satellite over Yellow Sea

The Coast Guard added that the satellite, if launched, was likely to fall outside of Japan's exclusive economic zone.

North Korea launched a satellite on May 31 that ended up plunging into the sea. The new Chollima-1 satellite launch rocket failed because of instability in the engine and fuel system, state news agency KCNA reported.

The flight was the nuclear-armed state's sixth satellite launch attempt, and the first since 2016. It was supposed to put North Korea's first spy satellite into orbit.

It prompted emergency alerts and brief evacuation warnings in parts of South Korea and Japan but no danger or damage was reported.
