North Korea making preparations to attack South, says spy agency

North Korean leader Kim Jong Un has ordered preparations for launching attacks on South Korea, Seoul's spy agency disclosed, as worries about the North grow after its recent nuclear test and rocket launch.

In a private briefing to ruling Saenuri Party members, the National Intelligence Service said the North's spy agency has begun work to implement the order to "actively muster capabilities" to carry out cyber and other attacks on South Korea.
