NATO Secretary-General Jens Stoltenberg on Thursday said he condemned North Korea's failed satellite launch, adding he called upon the country to "cease these provocative actions."

A North Korean satellite launch on Wednesday ended in failure, sending the booster and payload plunging into the sea, North Korean state media said.

North Korea's Kim Yo-jong, leader Kim Jong-un's sister, said her country would soon put a military spy satellite into orbit and promised Pyongyang would increase its military surveillance capabilities, state media KCNA reported earlier on Thursday. (Reuters)
