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 on Thursday. The remarks by Kim, a powerful ruling party official, came a day after a failed attempt at launching the country's first spy satellite, which plunged into sea, Reuters said. Kim rejected condemnation of the launch by Washington and other countries as an infringement of its sovereign right to space development.
