A North Korean satellite launch on Wednesday ended in failure, sending the booster and payload plunging into the sea, North Korean state media said, and the South's military said it had recovered parts of the launch vehicle.
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 in orbit.
The rocket plunged into the sea "after losing thrust due to the abnormal starting of the second-stage engine," KCNA reported, in an unusually candid admission of a technical failure by the North.
Pyongyang's National Aerospace Development Administration (NADA) will investigate the "serious defects" and take action to overcome them before conducting a second launch as soon as possible, KCNA said.
