Story highlights North Korean troops take part in drills reportedly designed to simulate attack on South

News of war games comes as South Korea experiences political upheaval

Seoul, South Korea (CNN) South Korea has strongly condemned North Korean military drills designed to simulate an attack on the South, a Unification Ministry spokesman told reporters in a regular briefing Monday.

North Korean leader Kim Jong Un on Sunday guided a combat drill by a special operation battalion, state media reported.

Photos published in North Korean newspaper Rodong Sinmun appeared to show a mockup of South Korea's presidential Blue House as a target.

Kim Jong Un purportedly supervises war games designed to train troops for an invasion of South Korea.

"Well done, the enemy troops will have no space to hide themselves, far from taking any counteraction," Kim reportedly said after watching the drill, according to North Korean state media KCNA.

The report specifically mentioned the South as a target for North Korean forces, as Kim offered advice on a "guerilla warfare" invasion of the country's southern neighbor and rival.
