SEOUL, Feb 19 (Reuters) - North Korea's Kim Yo Jong, the sister of leader Kim Jong Un, said she highly regards South Korea's official recognition of drones sent into North Korea, state media KCNA said on Thursday.
Kim said it is for South Korea's preservation to prevent the recurrence of such severe infringement of North Korea's sovereignty, and North Korean military will take measures to strengthen vigilance on the border with South Korea.
"The border with the enemy should be solid," Kim said, according to KCNA.
